I wanted to add one thing about colors : No color exists really as we see it. It depends only on the wave-length of the light, and our (your) brain "
shows" you a color. (
show is not the good word, but I don't know what I could say, to be more correct)
Humans have 3 kinds of color-captors (they are called cones) in their eyes (red-blue-green : Guess why our screens work that way too), so all colors we see are a mix of these colors.
The red captor will be exited, when a light has some special wave-length (around 700 nm), and the two other captors will be exited at other wave-length.
Black is the result, when none of these cones are exitet by the light (that happens when there is no light, or when there is invisible light, like UV or Infra-Red, because the wave-length are not into the captors-range).
White is when the three captors are exited by the light to the maximum.
Between, some animals have 4 captors, so they "
see" other colors than humans.
And other animals, only have one, so they only see
Light or
No Light or
some ligth or
a lil more light.
That was for the explanation.
