Gather Supplies: Watercolour paints, brushes, paper, palette, water container, paper towels

To begin your watercolour colour wheel project, it's essential to gather all the necessary supplies. Start by selecting a set of watercolour paints that includes the primary colours: red, blue, and yellow. These primaries will serve as the foundation for mixing secondary and tertiary colours on your wheel. Opt for high-quality paints, as they tend to have richer pigments and better blending capabilities. Both pan and tube watercolours are suitable, but tubes often provide more vibrant and concentrated colours, which can be advantageous for this project.

Next, choose the right brushes for the task. A medium-sized round brush (e.g., size 6 or 8) is ideal for painting the colour wheel, as it allows for both precision and smooth colour application. Additionally, having a smaller detail brush (size 2 or 4) can be helpful for finer work or corrections. Ensure your brushes have soft, absorbent bristles, typically made from synthetic fibres or natural hair, to handle watercolour paints effectively. Clean your brushes thoroughly before starting to avoid any colour contamination.

Selecting the appropriate paper is crucial for watercolour painting. Use cold-pressed watercolour paper, which has a slightly textured surface that holds paint well while allowing for smooth colour blending. The paper should be at least 140 lb (300 gsm) in weight to prevent warping or buckling when wet. If you're new to watercolours, consider practising on cheaper paper before using your final sheet for the colour wheel.

A palette is essential for mixing your colours. You can use a traditional watercolour palette with wells for each colour or a flat surface like a ceramic tile or plastic palette. Ensure your palette has enough space to mix primary colours into secondary and tertiary shades. Keep it clean and organised to maintain the purity of your colours. If using a reusable palette, rinse it thoroughly between sessions to avoid muddied colours.

A water container is a must-have for watercolour painting. Use a jar or container large enough to hold ample water for rinsing your brushes. It’s helpful to have two containers: one for cleaning brushes and one for keeping clean water for diluting paints. Change the water frequently to avoid contaminating your colours with residual pigment. Additionally, keep paper towels or a clean cloth nearby for blotting excess water from your brush and for quick clean-ups.

Finally, organise your workspace to ensure everything is within easy reach. Lay out your paints, brushes, paper, palette, water containers, and paper towels in a logical order. A well-prepared workspace not only makes the painting process smoother but also enhances your overall experience. With all your supplies gathered and ready, you’ll be fully prepared to dive into creating your watercolour colour wheel.

Mix Primary Colours: Combine red, blue, yellow to create secondary colours accurately

To begin mixing primary colours and creating secondary colours accurately for your watercolour colour wheel, start by gathering your primary colours: red, blue, and yellow. Ensure you have high-quality watercolour paints, as the pigment concentration and transparency will significantly affect the final results. Use a clean palette with separate wells for each colour to avoid contamination. Begin by wetting your paintbrush and loading it with clean water, then gently mix each primary colour on your palette to create a consistent, fluid paint. Remember, the key to accurate colour mixing is maintaining the right balance of water and paint, so adjust as needed to achieve a smooth, even consistency.

When mixing primary colours, it's essential to understand the colour relationships and ratios required to create accurate secondary colours. To create orange, combine yellow and red, starting with a higher ratio of yellow and gradually adding small amounts of red until you achieve the desired shade. Be cautious not to add too much red, as it can quickly overpower the mixture. For green, mix blue and yellow, beginning with an equal ratio of both colours and adjusting as needed. You may find that certain blues have a tendency to lean towards purple, so choose a blue with a greener bias for a more accurate green. To create purple, combine red and blue, starting with a higher ratio of blue and gradually adding red until you reach the desired hue.

As you mix your secondary colours, take note of the colour biases of your primary paints. Some reds may lean towards orange or purple, while some yellows may lean towards green. Understanding these biases will help you adjust your mixtures accordingly. For instance, if your red leans towards purple, you may need to add more yellow when creating orange to counteract the purple undertone. Similarly, if your yellow leans towards green, you may need to adjust your blue when mixing green to avoid an overly bluish hue. Practice mixing your secondary colours in small batches, making adjustments as needed, until you achieve consistent and accurate results.

To ensure accuracy in your colour mixing, use a clean brush for each new mixture and avoid cross-contamination between colours. You can also use a separate palette or designated areas on your palette for each secondary colour. As you work, observe the colours in natural light, as artificial lighting can alter their appearance. Take your time and be patient, as accurate colour mixing requires practice and attention to detail. Consider creating a colour mixing chart to record your ratios and observations, which will serve as a valuable reference for future projects. With practice, you'll develop a better understanding of colour relationships and be able to create a wide range of hues for your watercolour colour wheel.

When you've successfully mixed your secondary colours, it's time to refine and adjust them to achieve the desired saturation and value. If a colour appears too light, add small amounts of the primary colours used to create it, being careful not to alter the hue. If a colour appears too dark or muddy, add small amounts of water to lighten it, or mix a new batch with adjusted ratios. Remember that watercolour paints can be layered, so you can build up colour gradually by applying multiple washes. As you refine your secondary colours, keep in mind the overall balance and harmony of your colour wheel, ensuring that each colour is distinct and accurately represents its place in the spectrum. With careful attention to detail and practice, you'll be able to create a beautiful and accurate watercolour colour wheel that showcases your colour mixing skills.

Create Secondary Hues: Blend primary colours to form green, orange, purple

To create secondary hues in your watercolour colour wheel, you'll need to blend primary colours in specific combinations. Start by ensuring your palette is set up with the primary colours: red, blue, and yellow. These will be the foundation for creating green, orange, and purple. Begin with clean brushes and a clear mixing area to avoid contaminating your colours. For each secondary hue, you’ll mix two primary colours in equal parts, adjusting as needed to achieve the desired shade.

To form green, mix blue and yellow watercolour paints. Start by placing a small amount of blue on your palette, then add an equal amount of yellow. Use a clean, damp brush to blend the two colours together. The resulting green may vary depending on the specific blue and yellow pigments you use—some combinations will yield a warmer, yellowish-green, while others may produce a cooler, bluish-green. Experiment with different ratios if you want to adjust the tone, but always start with a 1:1 mix for a balanced green.

Next, create orange by blending red and yellow. Place a small amount of red on your palette and add an equal amount of yellow. Mix the colours with a clean brush, ensuring they combine thoroughly. The orange should appear vibrant and warm. If the orange seems too red, add a touch more yellow; if it’s too yellow, incorporate a bit more red. This step is straightforward, but precision in mixing ensures a pure orange hue.

To make purple, combine red and blue. Start by placing a small amount of red on your palette, then add an equal amount of blue. Blend the colours carefully with a damp brush. The resulting purple may lean more toward blue or red depending on the pigments used. For a cooler purple, use more blue; for a warmer purple, increase the red. Aim for a balanced mix initially, then adjust as needed to achieve the desired shade.

When blending, work with clean water and brushes to maintain the purity of each secondary hue. Watercolour is transparent, so layering or over-mixing can dull the colours. Once you’ve created green, orange, and purple, test each hue on a scrap piece of watercolour paper to ensure the tones are correct before applying them to your colour wheel. This step ensures your secondary hues are accurate and ready for placement between their corresponding primary colours on the wheel.

Paint the Wheel: Arrange colours in a circular pattern, leaving space for mixing

To begin painting your watercolour colour wheel, start by selecting your primary colours: red, blue, and yellow. These will be the foundation of your wheel. On your watercolour paper, lightly sketch a large circle using a pencil. Divide this circle into six equal sections, like a pie chart. Each section will represent a different colour, so ensure they are evenly spaced. The primary colours will occupy three of these sections, and the remaining spaces will be for the secondary colours you create by mixing.

Next, arrange your primary colours in a triangular pattern around the wheel. For example, place red at the top, yellow to the bottom left, and blue to the bottom right. This arrangement ensures that the secondary colours (orange, green, and purple) will naturally fall between the primaries when mixed. Leave a small gap between each colour section to allow space for mixing and blending, as this is where the magic happens in creating your secondary and intermediate colours.

Once your primaries are in place, it’s time to mix and paint the secondary colours. To create orange, mix red and yellow on your palette and then apply it to the section between these two colours. Repeat this process for green (blue and yellow) and purple (blue and red). Use clean water and a separate brush for each colour to avoid muddying your mixtures. Paint each secondary colour neatly into its designated section, ensuring smooth transitions between hues.

After the secondary colours are complete, you’ll notice three additional spaces between them. These are for the intermediate colours: red-orange, yellow-orange, blue-green, blue-purple, red-purple, and yellow-green. Mix these by combining a primary colour with a neighbouring secondary colour. For instance, red-orange is made by mixing red with orange. Paint these intermediate colours into their respective spaces, blending them carefully to maintain a harmonious flow around the wheel.

Finally, ensure each section is painted with even, consistent washes of colour. Allow each layer to dry before adding more paint to avoid bleeding or mixing unintended colours. The goal is to create a clean, vibrant colour wheel that showcases the relationships between hues. Leave ample space between sections to maintain clarity and highlight the gradual transitions between colours. This arrangement not only helps you understand colour theory but also serves as a useful reference for future watercolour projects.

Add Tertiary Shades: Mix secondary and primary colours to complete the wheel

To add tertiary shades and complete your watercolour colour wheel, you’ll need to mix secondary colours with their adjacent primary colours. Tertiary colours sit between primary and secondary colours on the wheel, creating a seamless transition. Start by identifying the secondary colours you’ve already mixed: orange, green, and purple. Next, take a clean brush and palette, and begin mixing each secondary colour with the primary colour to its left and right. For example, mix orange with red to create red-orange, and orange with yellow to create yellow-orange. Use a 1:1 ratio initially, adjusting as needed to achieve the desired shade. Keep your mixtures clean by rinsing your brush thoroughly between colours to avoid muddying the hues.

Once you’ve mixed red-orange and yellow-orange, move to the green section. Mix green with blue to create blue-green, and green with yellow to create yellow-green. Again, start with equal parts of each colour and refine the shade by adding more of one colour if needed. Tertiary colours should be vibrant and distinct, so ensure your pigments are well-saturated. Practice consistency in your mixing to maintain uniformity across the wheel. Label each tertiary shade lightly in pencil next to its section on the wheel to keep track of your progress.

Proceed to the purple section, mixing purple with blue to create blue-purple and purple with red to create red-purple. Tertiary shades often require subtle adjustments, so take your time to observe how the colours blend. Watercolour can be transparent, so layer your washes if needed to deepen the hues without overloading the paper. Use a small brush for precision, especially when painting the tertiary sections, as they are typically narrower than the primary and secondary segments.

As you paint each tertiary shade onto the wheel, ensure smooth transitions between colours. Start with a light wash and build up the intensity gradually, allowing each layer to dry slightly before adding more pigment. This technique prevents the colours from bleeding into each other and maintains the clarity of each tertiary shade. If you notice any uneven edges, use a clean, damp brush to gently soften the lines between colours.

Finally, step back and assess your colour wheel. Tertiary shades should bridge the gaps between primary and secondary colours harmoniously. If any tertiary colour appears too muted or mismatched, remix the shade and apply a corrective layer. Once you’re satisfied, allow the wheel to dry completely. Adding tertiary shades not only completes the colour wheel but also deepens your understanding of colour relationships, making it an essential step in mastering watercolour mixing techniques.
