Question:

why do lighter colors reflect more light?

Why do light colors reflect more light than darker colors?I already know that white absorbs less colors therefore reflects more and black, its the oppositeBut my teacher is asking WHY its like that? Why does it work that way? Anybody know?

Answer:

Let's take blue and light blue. Blue is a solid color that absorbs every single color and reflects blue. Light blue is not a solid color; it has blue AND it has white mixed in to make it brighter. In essence, the light blue mixture color is more brighter than the blue color because of its component of white. Because white reflects more, blue has no element of white (figuratively) and light blue has a component of white, it is safe to assume that light blue will reflect more than blue will. Light blue may not reflect as much as pure white, but it certainly will reflect more than solid blue because of light blue's white component. Cheers!
The darker a color is, the more black is mixed into the color. When you look a red apple, you see red because when light hits the apple, all the colors except for red get absorbed and only the red color is bounced back from the apple into your eyes. So you only see red coming from the apple. Black in essence is a color that does not reflect any light. So when you see something black you are not seeing any colored light bounce back from it; on the other hand white objects reflect all the colors back because white is a combination of all the colors of light. Dark colors then, since they have more black in them than white, will absorb more colors, and lighter colors, since they have white, will reflect more.
