One of the most troublesome aspects of painting is anticipating how your color will look once it dries. Too often, we put up a color we adore, only to discover it looks completely different a few hours later.
This phenomenon can ruin all the time spent choosing the perfect paint for your home gym, bedroom, kitchen, or even your entire house.
In this guide, learn why interior and exterior paint dry darker than its particular wet paint color and how to make sure your paint color dries to the exact shade you expect.
Paint dry darker shade is the most common scenario, especially if you’re using oil, latex, or acrylic paint. This is also true of paints containing gloss. Flat paint or matte paints, on the other hand, will often appear lighter after drying.
Does latex paint dry darker or lighter?
Usually, latex paint color dry darker once dried because the emulsion in the formula “hides” the paint’s true sheen. This means less light bounces off the painted surface when the paint wet, and more when it’s dry.
Because the polymer emulsion has clarified and hardened (producing a shinier surface), the color appears darker and more intense.
Does exterior paint dry lighter or darker?
Exterior paints are usually latex, which not only takes a while to dry but also appear darker. Exterior paint color also tend to look lighter when dried, simply because there’s so much natural light outdoors.
When selecting an exterior paint colors chip, you’re often in a hardware or paint colors store under artificial lighting, so the result will look quite different in real life.
What’s more, exterior painting projects tend to be quite large, like houses or garages. It’s hard to predict what such a broad area of color will look like until the project’s done, which can skew your perception of the color.
Maybe that light blue looked perfect in a chip or test patch, but not on a three-story house.
Does paint dry darker or lighter on walls?
When you apply interior paint a room a new color, too many factors are at play to predict how the paint color will appear when dry darker or lighter colors. Formulation, lighting, the pre-existing color on the walls, and your interior paints glossiness (or lack thereof) will all dictate your final result.
Why does paint dry lighter or darker than a color swatch?
A paint chip, sometimes called a paint swatch or color swatch card, is meant to represent the final result after a primer and multiple coats (if applicable) and usually shows the color with a matte or dirty eggshell paint finish or eggshell finish.
Once your paint is mixed properly, you might select a different glossiness level or even a different formula based on your project, both of which will affect how the color looks once dry i.e. dry lighter or darker.
Another factor to consider is that paint chips are perfectly smooth paper. Therefore, they can’t account for the texture or previous color of real walls, contributing to the final result.
Factors That Affect The Color Of Paint When It Dries
Unfortunately, you can’t always predict what will affect the color as the paint dries darker or lighter—but knowing those factors ahead of time can help you choose a paint type and environment that will deliver a result closer or identical to what you’re expecting.
This is how much gloss paint or semi gloss paints, if any, your paint contains. It affects the way light bounces off your surface, which largely dictates how vibrant the pigment looks.
How much light is in a given space, as well as what kind it is, will affect how the color looks. Certain bulb types such as LED or fluorescent will cast different tones and brightnesses of light.
Additionally, artificial lights, in general, look totally different from natural sunlight. This is known as illuminant metamerism: when two things look like the same color under one source of light but differ under another source.
The formula of your oil paints can dramatically affect its drying color. Water or oil paint (the most common solvents in paints) refract light when the paint is still wet, then evaporate; this is the paint drying.
Depending on your oil paints gloss and solvent type, this “wet paint refraction” might be more or less than its “dry refraction,” resulting in a lighter or darker appearance of oil paints or oil based paint, respectively.
Psychological factor/optical illusion
Different backgrounds can make a color swatch look lighter or darker. If you hold a paint swatch color up to a wall or other surface, the pre-existing color can alter your perception. For instance, holding a blue swatch color up to a green wall will look very different when you hold it up against a purple wall due to the contrast.
Tips To Ensure Your Paint Dries The Color You Expect
Few aspects of a renovation are as frustrating as poring over paint samples and swatches, then discovering it doesn’t look at all like you envisioned when your freshly painted wall dry.
Before you purchase an ounce of paint or paint sample from a paint store, consider these 5 tips to help make sure your paint dries darker or lighter, the exact color of your swatch or paint chip.
- 1Use a primer first.
Not only will a primer cover the old paint on the wall—so you’re not trying to cover a dark blue with a light pink, for instance—but it will also increase the adhesion of your topcoat to the wall, resulting in stronger pigments and better-looking results over time. And, if you use a tinted primer specifically made to match your topcoat, the resulting color will be even more vibrant.
- 2Paint when the air is 60°F or higher, and humidity is around 50%
These are the ideal conditions for paint to dry darker or lighter. Low humidity and warm temperatures ensure the solvents in your paint will evaporate steadily and completely, leaving behind only your pigment and any gloss components.
- 3Stir the paint well, and don’t use old paint
Using paint without stirring it might result in uneven amounts of the formula getting distributed on the wall. Too much gloss might occur in one spot, while another looks flat or streaky, giving the room a mottled, inconsistent appearance.
- 4Skip touch-ups whenever possible
Pigments can faded paint over time due to element exposure, skin or furniture contact, smoke, and more. Painting a small part of your wall years later will leave fresh pigment on one spot, making the contrast between old and new all the more obvious. If you have to re-paint an area, it’s better to coat the entire wall.
- 5Pay for high-quality formulas
Cheap paints typically have formulas that degrade faster, don’t blend as well, or come from companies that put less effort into truly matching their swatches to the paint’s final color. Investing in a high-quality brand will ensure your paint mixed properly thoroughly, adheres well, stands the test of time, and reliably correlates with its swatch.
How long until paint dries to its true color?
The time a paint takes to dry to its true color can vary depending on several factors, including the type of paint, the thickness of the application, the humidity and temperature of the environment, and the color of the paint itself.
It’s important to note that “dry to the touch” isn’t the same as completely dry.
Oil-based paints dry to the touch in up to eight hours, but take 24 hours to fully dry or take another coat. By contrast, latex paints can be touched after about one hour, and recoated in four.
Note that dry times reduce when using a paint sprayer instead of a roller or brush: latex takes just 10 to 30 minutes to achieve touch-dryness, while lacquer or epoxy paints can take a mere 5 minutes.
Paint Drying Darker Or Lighter FAQs
Should I wait for my paint to cure before judging its color?
No, you do not need to wait for the paint to fully cure before judging its final color because the difference is so slight.
Technically, this time period—7 days for oil-based paints, but 30 for latex varieties—has to pass before you see the “final color,”
Can you wait too long between coats of paint?
Yes, it is possible to wait too long to apply a second coat. Once the first coat has started to cure, it can affect how well the second coat adheres, resulting in chipping or peeling. Wait about 24 to 48 hours for second or third coats, depending on your paint’s instructions.
Why does my grey paint look blue?
Grey paints look blue because it can have a blue undertone (along with green or purple). In certain lighting conditions, this undertone becomes more prominent, giving grey paints a bluish appearance.
Does a third coat of paint make it darker?
No, third coat of paint won’t darken your walls, but it can result in a more vibrant color. If you want the paint to appear darker, consider adding a topcoat with more gloss, as this will reflect more light.
Does adding water to paint make it lighter?
Yes, adding water into paint will result in a lighter color once dried due to the dilution of its formula. By increasing the water (the solvent), you get a lower concentration of pigment spread across your surface.
Paint can dry darker or lighter due to many factors, including formula, lighting, contrast, and gloss content.
Using a primer and investing in high-quality paint are two steps you can take to mitigate this effect and help ensure your paint dries to a color close or identical to your swatch.
