Gentle Watercolours: Painting Flowing Rivers

Capturing the gentle movement of a river in watercolour requires a thoughtful approach to composition, colour, and technique. In this tutorial, we'll explore how to paint a river with a soft, fluid appearance that draws the viewer's eye and conveys a sense of depth. We'll discuss the importance of tilt and angle in creating the illusion of movement and learn how to use wet-in-wet painting to suggest blurry reflections. By incorporating a range of greens and blues, we'll bring the river scene to life, highlighting the interplay of light and shadow in the water and along the riverbank. With careful planning and attention to detail, you'll be able to create a watercolour river that flows gently across the page.

Sketch the composition, tilting the paper to encourage paint to flow in the right direction

To paint a river in watercolour, you'll first want to sketch out the composition. This will help you place the elements of your painting in the right spots. You don't need to sketch in too much detail, just enough to guide you. Place your sketch on an easel and tilt your painting up at an angle of 25 degrees or more. This will encourage the paint to flow downwards, which is the direction you want your river to flow in.

Tilt your paper at an angle to guide the paint flow. This technique is especially useful when working with wet paint on wet paper to create blurry-looking water reflections. You can tilt the paper to guide the colours in the direction you want them to flow. This will help you create the desired blurry effect for the water.

As the wet paper dries, you'll notice that the colours soften and lighten. This is a great way to create a subtle sky and river. If you want to add trees and grass, wait for the paper to dry completely before wetting those specific areas. By only wetting the areas where you want the paint to flow, you can control the direction and create more defined shapes.

For the river, you can use a mix of blues and greens, with some purples added while the paper is still wet to create those blurry reflections. You can also leave some unpainted white paper to represent cloud shapes and the colour of the sky reflecting on the water. Don't worry if this looks blurry at first, as you can add more definition later.

Overall, tilting your paper at the right angle is a simple yet effective technique to guide the flow of your paint and create the desired effect for a gently flowing river.

Paint the sky with blues and cloud shapes

To paint the sky in a watercolour river scene, you'll need a no. 4 mop brush and some Pthalo Blue paint. Start by painting the sky with the Pthalo Blue, leaving some "cloud shapes", or unpainted areas of white paper. Don't worry if the colour is very strong at this stage, as it will lighten as it dries. Tilt your painting at an angle of 25 degrees or more, so that the paint will flow downwards.

Allow the paper to dry completely. The cloud shapes will soften as the paint dries, creating a soft, subtle sky. Once dry, you can move on to the next stage of the painting, adding trees and grass.

Before you begin painting the trees and grass, wet the areas where they will be located. By only wetting these areas, you limit the flow of paint to those sections. Mix a range of greens by combining Gamboge Hue and Ultramarine initially for a light to mid-green, then add Prussian Blue and Paynes Grey to create darker tones.

You can also add some purple to the river to create blurry reflections. Tilt the paper to encourage the colours to flow where you want them. Use a small piece of scrunched-up dry tissue paper to lift the paint in various spots, creating realistic-looking "sky holes" and water sparkles.

Finally, let the painting dry completely before adding darker mid-ground trees and bushes in the foreground. Repeat the process of painting clean water only in the areas where the bushes will be, then adding paint to those sections.

Add greens and purples to the river while the paper is still wet

To add greens and purples to a watercolour painting of a gently flowing river while the paper is still wet, you can follow these steps:

Firstly, you will need to prepare your materials. For this step, you will need watercolour paper, a no. 4 mop brush, and green and purple watercolour paints. You can create green shades by combining Gamboge Hue and Ultramarine initially for a light to mid-green, then adding Prussian Blue and Paynes Grey for darker tones. For purple, you can use Dioxazine Purple.

Once you have your materials ready, you can start by dropping some green and purple paints onto the wet paper in the river area. This wet-on-wet painting technique creates blurry-looking water reflections. You can tilt the paper to guide the colours to flow in the desired direction, adding more paint as needed to achieve the desired effect.

To create more defined highlights and add depth to your painting, use a small piece of scrunched-up dry tissue paper to lift paint from various spots. This technique creates realistic-looking "sky holes" and water sparkles, adding contrast and texture to your river.

Let the painting dry completely before moving on to the next steps. In the following layers, you can add darker mid-ground trees and bushes, repeating the process of wetting the paper only in the desired areas to control the flow of paint.

By following these steps and allowing the paint to flow and blend naturally, you can create a beautiful and gentle river scene in watercolour.

Use diluted blues, oranges and yellows for the river bank

When painting a river in watercolour, it's important to consider the colours you use for the river bank to create a sense of depth and perspective. Using diluted blues, oranges, and yellows for the river bank can add interest and variety to your painting. Here's a step-by-step guide to help you achieve this effect:

Start by tilting your paper at an angle of 25 degrees or more when painting the river bank. This will ensure that the paint flows in the direction of the river's path, creating a sense of movement and fluidity.

For the river bank, choose a combination of blues, oranges, and yellows and dilute them with water to create a creamy consistency. You can adjust the dilution to control the intensity of the colours. This mixture will help you achieve a range of shades and tones to add depth to your painting.

Using a brush, gently apply the diluted colours to the river bank, moulding your brushstrokes to follow the contours of the bank. Leave some white areas to create highlights and give the illusion of sunlight reflecting off the water. Experiment with different brush pressures and techniques to create varied textures along the river bank.

As you work, allow the colours to blend and interact with each other. Don't be afraid to let them "bubble and boil" over the surface, as this will create interesting textures and add depth to your painting. You can also use a tissue to lift paint from certain spots, creating "sky holes" and adding further dimension to your artwork.

Once the river bank is established, you can begin to work on the finer details, such as boulders and foreground elements. Use stronger, creamier mixes of your chosen colours to build up the shapes and textures of these objects, ensuring they stand out against the softer background.

By following these steps and using diluted blues, oranges, and yellows, you can create a vibrant and captivating river bank in your watercolour painting, adding depth and interest to your artwork. Remember to experiment and adjust colours as needed to achieve your desired effect.

Create foam highlights and sparkles in the water with a creamy white gouache

To create foam highlights and sparkles in the water, use a rigger brush and some creamy white gouache. Start by using a fairly dilute mix, which will dry to a fairly muted white. Then, go in with a stronger mix, which will be much whiter, and flick some paint into the spray areas. Be careful not to overdo it—just a little here and there will emphasise the motion and add some sparkles.

You can also create realistic-looking "sky holes" and water sparkles by gently pressing a small piece of scrunched-up dry tissue paper onto the still-wet paper and strategically lifting the paint in various spots. This technique will create a blurry, fuzzy look to the water reflections.

Allow the gouache to dry completely before moving on to the next phase, which may involve adding darker mid-ground elements such as trees and bushes. This will involve repeating the previous process of painting clean water only in the areas where these elements will be added.

Remember to step back and assess your work as you go, making adjustments as necessary to create a sense of depth and perspective in your painting.
