If you must choose, then out of Yellow, Magenta and Cyan...

I'm asking, because I want to know if people see colors the same way as I do.
If my "red" is your "green" I expect different answers.

^1^ Primary colors are Red, Green and Blue.

Yellow, Magenta and Cyan are not really "in between" 2 primary colors. More like a sum of 2 primary colors.

We can explore this with the RGB color space model.

R G B
1 0 0 - red
0 1 0 - green
0 0 1 - blue 
1 1 0 - yellow
0 1 1 - cyan
1 0 1 - magenta
1 1 1 - white
0 0 0 - black

So you can see for instance that yellow is actually 2x as "bright" as red. In this model, white is 3x as bright as red.
