Are Shades Considered Colors? And Can Someone Be Allergic to a Color?

[Odin]

Is anybody else here confused? In my town half the people seem to believe black, white and grey are colors? Could anyone clarify? Much obliged...
A color or a shade?

 

[honestrosewater]

What definition of "color" has everyone in your town agreed to use? ;)

Concerning color addition, half the people are right.
Concerning color subtraction, the other half are right.
So, they're all right, right?

I don't like colors. They confuse me.

I think I'm allergic to green... especially after that "why you shouldn't stare" thread...
