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 paint dries darker or lighter than its wet color and how to make sure your paint dries to the exact shade you expect.
Unfortunately, you can’t always predict what will affect the color of your paint as it dries—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, 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 paint can dramatically affect its drying color. Water or oil (the most common solvents in paints) refract light when the paint is still wet, then evaporate; this is the paint drying.
Depending on your paint’s gloss and solvent type, this “wet refraction” might be more or less than its “dry refraction,” resulting in a lighter or darker appearance, respectively.
Psychological factor/optical illusion
Different backgrounds can make a swatch look lighter or darker. If you hold a swatch up to a wall or other surface, the pre-existing color can alter your perception. For instance, holding a blue swatch up to a green wall will look very different when you hold it up against a purple wall due to the contrast.
So, Does Paint Dry Lighter Or Darker? (Well, It Depends)
Drying darker is the most common scenario, especially if you’re using oil, latex, or acrylics. This is also true of paints containing gloss. Flat or matte paints, on the other hand, will often appear lighter after drying.
Does latex paint dry darker or lighter?
Usually, latex paint will appear darker once dried because the emulsion in the formula “hides” the paint’s true sheen. This means less light bounces off the surface when the paint is 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?
Oddly, even though exterior paints are usually latex—which can often dry darker—exterior paints tend to look lighter when painted, simply because there’s so much natural light outdoors. When selecting a paint chip, you’re often in a hardware or paint 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 paint a room a new color, too many factors are at play to predict how the paint will appear when dry. Formulation, lighting, the pre-existing color on the walls, and your paint’s glossiness (or lack thereof) will all dictate your final result.
Why does paint dry lighter or darker than a swatch?
A paint chip, sometimes called a 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 eggshell finish.
Once your paint is mixed, 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.
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.
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 walls dry. Before you purchase an ounce of paint, consider these 5 tips to help make sure your paint dries to 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. 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 fade 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 mixes thoroughly, adheres well, stands the test of time, and reliably correlates with its swatch.
People Also Ask (FAQs)
How long until paint dries to its true color?
First, it’s important to note that “dry to the touch” isn’t the same as completely dry. It simply means the outermost layer of the paint has dried, and the solvents have evaporated. But the rest of the formula hasn’t hardened yet—which means your final color has yet to reveal itself.
Oil-based paints dry to the touch in about 8 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.
Should I wait for my paint to cure before judging its color?
Curing involves the paint being absorbed (slightly) into the wall, and the compounds hardening to completion. Technically, this time period—7 days for oil-based paints, but 30 for latex varieties—has to pass before you see the “final color,” but the difference is so slight that waiting really isn’t necessary. As soon as your final coat has completely dried, you can judge the results.
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 paint 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. You might also find the paint looks bluer in the early morning or when compared to other colors in your decor.
Does a third coat of paint make it darker?
Adding a 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?
Mixing 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.
When thinning your paint with water, first ensure that the formula is water-based to begin with. Next, pour your paint into a bucket. Add room-temperature water a little at a time, stirring thoroughly after each addition. Don’t exceed 4 cups of water per gallon of paint; usually, you won’t need more than ½ to 1 ½ cups per gallon.
Paint can appear darker or lighter once dry 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.
