And, as you most likely know, the reverse is also true. If the Smiths' walls had been maroon to begin with, and you're asked to paint over them with a soft ivory, you'll have trouble on your hands if you don't block as much of the dark color with an off-white primer coat before you apply the finish coat. Not all issues of color concern interior projects. When your customer asks your opinion of exterior shades, there are also some general guidelines you can confidently share. Reds and yellows can have the potential to fade more quickly than blues and greens.
Blacks can turn hazy.
But the downside is that chalking whites can fade onto windows and masonry, and create streaks. Therefore, these whites can tend to show dirt more readily. The quality of light, depending upon geographical location, is also vital when selecting exterior colors. If your customer lives in a sunny southern climate, where the sun is closer and the natural light more intense, brights and midtones will work well. That's because these shades are most compatible with the sunlight level.
