People need color to see. Unlike cats, we see in color because we live in the daytime. Cats see in black and white and shades of gray because they are nocturnal.
Color is brain code for frequencies of light - compare a black and white picture with the same one in color and note the ease with which you can pick out features. So - color detects foods and enemies faster.
There are 52 shades of blue, cannt type that lot.
black is not a color it is just a shade :)
Eye color is a polygenic phenotypic character and is determined by the amount and type of pigments in the eye's iris. The genetics of eye color are complicated, and color is determined by multiple genes. In human eyes, these variations in color are attributed to varying ratios of eumelanin produced by melanocytes in the iris. Eye color is an inherited trait influenced by more than one gene. These genes are being sought using associations to small changes in the genes themselves and in neighboring genes

Shades of a color are when you mix a little black with it, at least, in art.
Black by definition is the absence of light. However in a real world setting people can not replicate that accurately, so there for there are different attempts that fall within the category of "Black". There are hundreds of different shades of black.
You can't mix two colors to get blue, but you can use blue and white to get light shades of blue and black to get dark shades.
No, most things do. Other things have shades (black and white).

Chiaroscuro is a monochrome picture made by using several different shades of the same color.
Black and white are colors, but technically both can be the absence of color, or the total combination of colors. B&W television used shades of gray (although that might also qualify as a color). The term "color TV" means a "full spectrum of colors" rather than simply grays.
