1 reason why every single powder room will look grey ish if you just slap up some generic white light off white.
Wall paint that changes color in light.
As a rule higher gloss paints tend to enrich and brighten color.
This is why you can paint walls in an entire home with identical floors trims the very same color but with whites off whites the paint will change colors in every single room if the lighting exposure is different which in 99 of homes of course the exposures are different.
Light colored walls can reflect the colors of bold carpets.
A bright blue rug for instance can cast a bluish tone on a white wall.
If the windows of your room face north the natural light will add blue to the wall paint colors.
A general rule of thumb is that if your room is north facing it will let in soft light producing a warm effect.
Colorful ceiling designs and wall painting the same color decrease a space visually and make a room look small and cozy.
Eastern exposure adds green.
Paint sheen also affects color.
And here s something to keep in mind if you are going to use tinted light shades in the room.
Dark color combined with light walls bring the ceiling down.
Glossy finishes will reflect light and change the way the color looks whereas flat finishes are less reflective and allow colors to look truer under bright light.
Two color walls and light ceiling stretch an interior horizontally.
Another paint characteristic that affects color and light is gloss level.
The color of the light will either intensify the wall paint color if it s from the same color family or dull it if it s a complementary color.
On the other hand if the room receives south facing light exposure it will have much more intense light.
This means dark paints will look darker and light paints will be more dim.
A green lawn in summertime and evergreens in the winter can also cast a green.
