Why Your Colour Match Looks Different in Different Light
Paint colour matched in a store can look different in your home due to a phenomenon called metamerism, where colours appear to change under different light sources. This happens because various light types-natural daylight, incandescent, LED-emit different wavelengths, which interact with the pigments in the paint to alter how your eyes perceive the colour. What looks perfect under the store's bright, cool lighting might shift to appear warmer or cooler, or even a subtly different hue, once applied in your living room or kitchen in Smiths Falls.
The science of metamerism
Metamerism is a fascinating aspect of colour science that explains why two colours that appear to be a perfect match under one light source can look completely different under another. This isn't a flaw in the paint or the colour matching process; it's a fundamental property of how light, objects, and our eyes interact. When paint is mixed, it's formulated to reflect light in a specific way. However, different light sources contain varying amounts of red, green, and blue light. When the light changes, the way those pigments reflect light back to your eyes changes too, leading to a perceived shift in colour. Understanding this phenomenon is the first step to avoiding surprises with your new paint colour.
How store lighting vs. home lighting affects your match
Paint stores typically use bright, often cool-toned, fluorescent or LED lighting to ensure accurate colour matching. This standardized lighting environment helps our spectrophotometer equipment give you a precise match to your sample. However, your home in Smiths Falls likely has a mix of natural daylight, warmer incandescent bulbs, or cooler LED fixtures. Each of these light sources will interact differently with your new paint. For example, a paint colour that looks crisp and clean in the store might appear softer and warmer under your home's incandescent lighting, or slightly cooler under natural light from a north-facing window. This difference isn't a mistake in the match, but a natural optical effect.
How to test your colour match in your own lighting
To ensure your colour match looks just right where it matters most, testing it in your home's actual lighting conditions is crucial. Our staff, some with over 20 years behind the counter, consistently advise customers to do this. Start by getting a small sample pot of your matched colour. Paint a generous swatch (at least 2x2 feet) on a piece of poster board or directly on a less conspicuous area of your wall. Observe this swatch throughout the day, in different rooms, and under various lighting conditions: morning light, afternoon sun, evening lamps, and even with curtains drawn. This allows you to see how the colour reacts to direct sunlight, ambient room light, and artificial light sources, helping you make an informed decision and avoid any post-painting regrets.

Don't Judge by a Tiny Chip
A small paint chip doesn't provide enough surface area to accurately assess how a colour will look on a large wall in varying light.
- 2
Avoid Direct Sample Comparison
Don't hold your sample chip directly against the wet paint. Let the paint dry completely, as wet paint often looks different than dry.

Neglecting Primer
The colour of the surface underneath can impact the final appearance of your new paint. Always use a quality primer, especially when changing colours dramatically.

Ignoring Sheen
Different paint sheens (flat, eggshell, semi-gloss) reflect light differently, which can subtly alter the perceived colour. Consider both colour and sheen.
Common mistakes to avoid
When dealing with colour matching and paint selection, certain mistakes can lead to disappointment. One common error is judging a colour solely under a single light source, such as the bright, consistent lighting of a paint store. Another mistake is failing to test a sample in the actual space where it will be applied. Many homeowners also overlook the impact of existing room elements like flooring, furniture, and natural light exposure on the final paint colour. Ignoring these factors can lead to a colour that feels 'off' once the project is complete. It's also easy to forget that the surrounding colours in a room can influence how a particular shade is perceived. By being mindful of these pitfalls, you can make a more confident colour choice for your home in Smiths Falls or Lanark County.

This is due to metamerism, where colours appear to change under varying light sources. Different types of light (natural, incandescent, LED) have different wavelengths that interact uniquely with paint pigments, causing a perceived shift in colour.
The best way is to test a sample pot of your chosen colour on a large swatch in your home. Observe it throughout the day under different natural and artificial lighting conditions before committing to the full project.
Related concerns
Beyond metamerism, other factors can influence how a paint colour appears in your home. The texture of your wall, the sheen of the paint (from flat to high-gloss), and even the colours of adjacent surfaces can all play a role. A highly textured wall might make a colour appear darker due to shadows, while a high-sheen paint will reflect more light, often making the colour seem brighter. The size of the room and the amount of natural light it receives are also critical. A small room with limited windows will absorb more light, making colours appear deeper, whereas a large, bright room might wash out a subtle shade. Considering these related concerns along with lighting effects will help you achieve the desired aesthetic for your space.
