well they'll "fool" the cones.
I have a bit of past experience indicating that to get white light, you
need:
1) Really good color mixing
2) Number of green LEDs roughly twice the number of blue ones, and number
of red LEDs roughly 3 times the number of blue ones. This will vary with
efficiency of your particular LEDs.
If you want a warmer shade of white, use fewer blue ones, replacing them
with red more than green.
So far in my experience, equal number of red, green and blue LEDs gives
a roughly sky blue color.
