If they look straight, they can see the color black. If they see a bright light through their eyelids, they can see the color white. Isn't white and black colors?

White and Black are not colors... they are "light" and "dark." Nothing to do with color blindness.
The site below has a color blindness test.

A blackening in the center of your vision is usually due to a condition called macular degeneration (MD). MD is a progressive disease of the eye that can result in total blindness.
Color blindness is a defficiency in the color sensing cells of your eye (cones)...usually red or green. Color blindness is congenital (you're born with it) and it does have a genetic component (meaning it is passed on through your family). Color blindness does not affect your ability to see objects...just to perceive color. You can still see things...think of it as having a black and white TV versus a color TV.
Black and white are not colors. Black and white is just the presence or absence of light when it comes to eyes.
