The funny part about color spaces being that you can't make (pure) cyan out of green and blue, which is exactly why CMYK is used over RYB in inks.
(I mostly think about colours in Hue-Saturation-Value terms, and a hue wheel of blue-cyan-green-yellow-orange-red-purple)
For subtractive colors (dyes) you're right. For additive (light), green and blue make cyan (Hex: #00FFFF)
