No matter if you are putting the paint on the drywall, wood, or any other surface, the paint will always seem a little darker when it dries.
Particularly oil, acrylic, or latex paints are known to get darker as they dry.
This simply means that even though they may appear identical once dry, they won’t look the same as what’s on the paint swatch you have looked at and chosen.
Remember that if you have mixed the paint properly before application and have given it enough time to completely dry (at least eight to ten hours), it should look the same as the color you picked after it dries.
But if the final appearance is not what you wanted, don’t despair.
You can always alter the shade by painting over it with a new color or making it darker or lighter as per your liking. This will, of course, require some more work on your part.
Does Paint Dry Darker or Lighter?
In short, most quality paints do not dry lighter or darker.
When the paint is applied, it may appear lighter or darker than anticipated; however, good paint should always dry to the color shown on the lid or swatch.
After the paint has dried on the surface and has been there for some time, the oxidization can turn the pigment in the paint darker with time.
This holds particularly true for oil-based enamel paints when used outdoors.
If you have used latex or enamel paints indoors, this change in color should not be noticeable.
Some latex paints, however, may show a slight color variation when applied in different coats on the same surface.
This is because the first coat usually absorbs more paint than subsequent coats, and this can make the dried paint appear slightly darker.
But in general, you should not worry about the paint drying darker or lighter than its intended color.
As long as you have used quality paint and have given it sufficient time to dry, the final color should be as expected.
Factors that Influence the Color of Paint as It Dries
Paint can look different when it dries than it does when first applied to the wall because of a number of factors.
The type of paint, the amount of pigment, the color of the undercoat, the porosity of the surface being painted, and even the time of day can all affect how the paint looks when it dries.
One factor that affects how the paint looks when it dries is the lighting. The paint will usually look darker in a room with less natural light and lighter in a room with more natural light.
This is because our eyes will generally adjust to the different levels of light, so a color that looks dark in a dim room will look lighter when we step into a brighter space.
Another factor that can affect the paint or stain color as it dries is the pigment.
The pigments are responsible for giving paint its color, and different pigments will dry to different colors.
Some pigments, like black or white, will dry to very similar colors regardless of the type of paint or the lighting conditions.
But other pigments, like blue or green, can look very different when they dry.
For example, a light blue paint might dry to a darker blue in a room with less natural light and a brighter blue in a room with more natural light.
The color of the undercoat can also affect how the paint looks when it dries.
If you’re painting over a dark blood red color, for example, the paint will usually look lighter when it dries.
And if you’re painting over a light color, the paint will usually look darker when it dries.
This is because the undercoat color will show through the paint, and our eyes will adjust to the different colors.
Besides the undercoat, the number of coats you apply will also have a big impact on whether the paint will dry darker or lighter.
This is because each coat will add a layer of pigment, and the more coats you apply, the darker the color will become.
4- Surface Porosity
Another important factor that can affect the color of the paint as it dries is the surface porosity.
Porosity is a measure of how much air can pass through a material, and different materials have different levels of porosity.
For example, wood is more porous than metal, so the paint will dry darker on a wood surface than it will on a metal surface.
This is because the paint absorbs into the porous wood, making it look darker.
5- Time of Day
The time of day can also affect how your wall paint will going to look after it gets dried.
Paint usually looks darker when it first goes on, and then it gets lighter as it dries.
So if you’re painting in the morning, the paint will look darker than if you’re painting in the afternoon.
This is because the paint dries slower in the morning, so it has more time to absorb into the surface and look darker.
In the mid-afternoon when the wet paint dries faster by evaporation, and the light reflects off of it differently as the water or other solvents evaporate.
6- Paint Finish
Remember that different colors, finishes, textures, and patterns tend to give various looks when applied to surfaces.
So, the finish of the paint also has an impact on how it looks once it’s dry.
For example, paint with a glossy finish will usually look darker than the swatch color you chose when it dries, compared to paint with a matte or eggshell finish.
On the other hand, there is flat paint that usually looks lighter simply because there is no shine at all, and the color can be seen more clearly.
7- Other Conditions
Besides the above, there are a few other conditions that can affect how the paint looks when after drying.
For example, if the humidity is high or the temperature is low, the paint will take longer to dry and will usually look darker.
Also, if you have indoor plants, furniture, or pictures on walls, the paint might look a little different because of the way the light reflects off these objects.
Other than that, there are psychological factors impacting your visuals, such as the type of colors you like or are used to seeing.
And this might result in your paint appearing darker or lighter than it really is.
Although there isn’t a big difference as you have chosen from a swatch, it’s something to consider if you’re trying to achieve a specific color.
How to Avoid the Paint Getting Darker or Lighter Than Expected?
To get an accurate idea of how the paint will look once it’s dry, it’s always best to test a small area first.
Get a sample pot of the paint color you want and paint a large swatch on your wall.
Then, wait for it to dry and see how it looks in different lighting conditions before you commit to painting the whole wall.
This way, you can avoid the entire rigmarole and make sure that you’re happy with the color and that it looks the way you want it to.
A few other tips that can help you avoid the color getting darker or lighter than expected include:
- Always use the primer
- Get high-quality paint from a premium brand
- Choose the correct paint finish based on the project needs
- Read the paint can label carefully for the pigments and ingredients
- Stir your paint thoroughly before you use it, and apply the paint under consistent conditions.
If you’re still not sure, you can always ask a professional painter for their opinion.
They will help you by giving more accurate advice on how the paint will look once it’s dry and what you can do to achieve the color you want.
Does old paint change in color?
Yes, paint can definitely change color over time. The type of paint, its quality, and how it’s been stored all play a role in how long the paint or stain will last before it will start to change color.
So, if you’re using old paint stored in your garage, it’s always best to test them on a small surface to see if the color hasn’t changed and as per your liking.
Why do some black paints look blue when wet?
The reason why some black paints look blue when wet is because of the way light reflects off of them.
When the paint is wet, the light reflects off of it differently than when it’s dry, and this can cause the color to appear different.
Also, certain waterborne black paints are known to have a bluish tin.
So, they look blue when first applied but ultimately get their original black color when they dry and set in on the surface.
Will UV damage make my exterior paint look lighter?
Yes, UV damage can make exterior paint look lighter. The ultraviolet rays of the sun can cause the paint to fade and change color over time.
This is why it’s important to choose paint that has good UV protection if you’re going to be using it on an exterior surface.
The bottom line
While there are many factors impacting the final look and color of your paint, if you have used high-quality paint and have applied it properly, the paint should look very similar to the swatch shade you selected.
Also, by taking the time to test the paint color first, you can avoid any surprises and be confident that you’ll love the way your walls look once they’re painted.
