Slightly darker and muted shades that tend toward the blue side of the color spectrum are called cool neutrals. These colors, when applied to metal and other roofing materials, do not absorb or reflect a great deal of heat from the sun. This means the color does not significantly increase or decrease the temperature of the home.

What does color light heat the best?

While light colors are resistant to gathering heat, black colors provide better protection fro the sun’s UV rays. This makes black and other dark colors an excellent choice for sunblocking power. Unfortunately, black does attract heat, so you’ll probably be the most comfortable wearing black on days that are sunny but not so warm.

How do colors absorb light?

Water absorbs colors of the light spectrum as light rays travel through the water, and this is called absorption. Red is the first color absorbed, followed by orange, yellow, green, blue, indigo, and violet.
