If white is the opposite of black then what is the opposite of gray?

Answer:

Brown I guess, I mean look at the color wheel, black is across from white and you can tell gray is next to white and brown is next to black so there you have it.

Answer:

The Word 'black' in the sense of a color or pigment has no opposite.

We routinely pair the color terms 'black' and 'white' in the sense of being opposite, or different, but while the concepts are indeed different, they aren't opposite, any more than are other commonly-paired Words such as 'cat' and 'dog'.

To be opposites, Words need to express opposing concepts. So, 'pale', or 'fair', can be the opposite of 'dark', while 'black' and 'white', like 'blonde' and 'brunette', or 'blue' and 'red', are diiferent, rather than opposing, pairs.
