For this puzzle we will assume the following
White is the presence of all color
Black is the absence of all color

Using the above, the color grey would be half way in between black and white.
What colors are used to make the color grey?

Half made of the shade that is almost white and half made of the shade that is almost black. This sounds too easy a solution though... hmm

Yep he does, but also makes a point of defining grey halfway between white and black.

This question is an example of confusing absence vis-a-vis presence in zero amount.
For more on that issue, read my rant about the abuse of ZERO here. ;)
