Paint colour can be affected by a variety of factors, including lighting, the type of paint, temperature, humidity, and the colour of the primer. When wet, paint appears darker due to reduced light reflection, but as it dries, the water evaporates, resulting in increased light reflection and a potential lightening effect. However, this can create an optical illusion where the dried paint still appears darker. Gloss finishes can cause paint to look darker, while matte or flat finishes will absorb more light, giving the paint a lighter appearance. Additionally, the concentration of pigments and the opacity of the paint can impact the perceived lightness or darkness of the dried paint.

Paint type, temperature, and humidity can affect the colour
Paint type, temperature, and humidity can all affect the final colour of a painting project.
Firstly, the type of paint you use will determine how the colour dries and appears. Paint comes in several finishes, each with a different level of sheen, or shine. The sheen measures how much light reflects off the paint. For example, semigloss paints have more sheen and are more reflective than satin finishes, so they can help darker rooms feel lighter and brighter. High-gloss finishes are the most reflective and will draw attention to the colour. The amount of pigment and additives in the paint will control the sheen.
Secondly, the temperature can affect the colour of the paint as it dries. High temperatures cause paint to dry very quickly, which can lead to lap marks and chipping. Direct sunlight can also bleach the paint colour, making patches and repairs more difficult.
Finally, humidity can also impact the final colour of paint. In high humidity, paint may run before it dries and may not hold well, especially on metal surfaces. This is because moisture from the air can condense on the metal and create a barrier between the surface and the paint. Humidity can also cause mildew to grow on exterior paint, especially in areas with less sun exposure.
Therefore, it is important to consider the outdoor conditions and choose the right type of paint to ensure the best outcome for your painting project.

Gloss finishes may give a richer, deeper appearance
Paint often changes shades as it dries, and the type of paint you use can determine whether it dries darker or lighter. Typically, wet paint will appear lighter than dry, which means that as the paint dries, the colour will darken.
The degree of sheen in paint can range from flat (no shine) to high gloss (extremely shiny). Satin paint, for example, has a lower sheen and a softer finish and is often used in areas that require both durability and a refined aesthetic, such as kitchens and bathrooms. Satin paint tends to soften colours, making them appear slightly muted but deeper and richer, especially with warm tones like taupe, beige, and terracotta.
The perception of paint colours can also change depending on the angle from which they are viewed, due to light refraction. When light hits the surface of gloss paint, it refracts or bends, altering the way the colour is perceived. This can result in a mismatched appearance when comparing two paint samples that are identical in colour but viewed at different angles. Therefore, when choosing paint finishes, it is important to consider the overall visual consistency of the painted space.

Matte finishes absorb more light, giving a lighter appearance
When it comes to paint, there are a multitude of factors that can impact the final colour and appearance. The type of paint, temperature, humidity, and lighting conditions can all affect the colour of the paint as it dries.
One of the most important considerations is the finish of the paint. Gloss finishes, for example, reflect more light, which can make the paint colour appear lighter and brighter. In contrast, matte or flat finishes absorb more light, giving the paint a lighter appearance. This is because matte finishes have a lower gloss level, resulting in reduced light reflection and a darker appearance.
Matte finishes are known for their ability to absorb light, which can enhance the depth and richness of the paint colour. This absorption of light gives matte finishes their distinctive look, as they lack the sheen and reflectiveness of gloss finishes. By absorbing light, matte finishes create a softer, more subtle effect, which can be particularly desirable for certain design aesthetics.
The absence of sheen in matte finishes also contributes to their unique appearance. Without the shiny surface created by gloss finishes, matte paints have a more subdued and understated look. This can be advantageous in situations where a less reflective surface is desired, such as in spaces with ample natural light or areas where a softer ambience is preferred.
It's worth noting that while matte finishes absorb more light, the surrounding environment and lighting conditions can still influence the appearance of the paint. Natural light, incandescent light, fluorescent light, and LED lighting can all alter the way a colour appears, so it's essential to consider the lighting of the space when selecting a paint colour and finish.

Primer colour can affect how paint appears during application and after drying
Wet paint typically appears lighter than when it is dry. As the paint dries, the colour will darken, and the painted surface should match the paint swatch from the manufacturer. The type of paint, temperature, and humidity can impact the paint colour as it dries. For instance, a gloss finish may give the paint a deeper appearance, but it can also make the colour look darker. Similarly, satin-finish paint often dries darker, while a matte or flat finish will absorb more light, giving the paint a lighter appearance.
The colour of the primer can also affect the final colour of the paint. For example, if you use a black primer under a white topcoat, you may need to apply more paint to prevent the black undercoat from altering the colour of the white. Tinted primers are now available in the same colour as the topcoat to address this issue.
It is essential to allow the primer to dry completely before applying the paint. The drying time varies depending on the type of primer, the surface being primed, and environmental factors such as humidity and temperature. Oil-based primers typically need 24 hours to dry, while latex primers can be ready in as little as one to three hours. Applying paint before the primer is fully dry can cause bubbling, alter the paint colour, and reduce overall drying times.

Sheen and lighting conditions can impact the paint's appearance
The sheen of paint, or its gloss level, can significantly impact its appearance. Gloss is about shine, or how much light is reflected from the painted surface. A flat or low sheen paint has a rough surface when it dries, causing light to scatter and the paint to appear "flat" to the eye. On the other hand, high-gloss paint has a smooth surface, reflecting light uniformly and appearing "shiny". The same colour with different levels of gloss will appear as different colours, with higher gloss making colours appear brighter and richer.
The level of gloss can also affect how paint colours appear under different lighting conditions. For example, a warm orange-red colour will appear brighter and warmer in a north-facing room with cooler, bluer light, but will become intensely vivid in a west-facing room with rich yellow or golden light in the late afternoon.
Lighting conditions can also affect how paint colours appear. Light rays bounce off paint differently depending on their wavelengths, altering the appearance of the paint. For example, dark colours will appear brighter under bulbs with higher colour temperatures, while light colours may appear washed out. Similarly, east-facing rooms will have lots of natural light in the morning, but will be darker later in the day, causing dark colours to appear drab as the light fades.
It is recommended to test paint colours in different areas of a room to see how they change under different lighting conditions.
