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?

All colors

let there be.......light in normal circumstances as colours by other mediums would be different. Therefore white light will reflect the colour of the object to the retina!

Half White and half black

Re read the puzzle. He defines black as the absence of color...

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.

But the question asks what colors are used to make grey

[itachi-san]

Since black is none and white is all, then grey is half the colors

For more on that issue, read my rant about the abuse of ZERO here.

Black, white and grey are all neutral.

That is, they have all colors present in equal amounts.

Black is only special among these in that the equal amount is zero.

Grey has all colors present; to a lesser degree than white, but non-zero.

This question is an example of confusing absence vis-a-vis presence in zero amount.

Grey is dark white.

Might be a speck on your lens ?

Which as opposed to what colours]Since in this puzzle the colour grey is half way between white/all colours and the absence of white/all colours = less than all white therefore will = grey depending on scale

Or intermittent white (a % of spacing) just like on ye old TV with the effect that you get on newspaper images.
