Name all of the colors in the world?

All of the colors in the world can be broken down to some form of the primary, secondary and tertiary colours on the colour wheel with the addition of the neutrals.

The primary colours are Red, Yellow and Blue.

The secondary colours are Purple, Green and Orange.

The tertiary colours are Red-purple, Blue-purple, Blue-green, Yellow-green, Yellow-orange, and Red-orange.

The neutral colours are, black, white, grey, and brown.

A guy friend of mine claims he can describe all the colours using just the colours you find in an eight pack of crayons and adding "ish" and "y" to them.

Using that theory, aqua would be a green-ish bluey colour.
