Download Retinal Rivalry Blend File Here.
I read up on all this stuff for retinal rivalry when looking at things through Anaglyph (Red-Blue) 3D Glasses. Retinal Rivalry is when colours look dark in one eye and bright in the other, leading to eye strain and maybe even swine flu.
In any case I found this article on a Dubois algorithm that they use on YouTube for 3d content. This basically turns you colour spectrum to a bunch of greys, yellows and purples - the only colours that don’t clash when wearing anaglyph glasses.
Here’s a picture of a standard set of colours and its Dubois counterpart.

I’ll put up more details on how I got these colours soon. I actually used Blender to seperate the colours and reconfigure them this way.
Check this out:
Method One
Pixels in a standard image are made out of a mixture Red, Green and Blue elements. The easiest way to deal with how to remix the colours for 3d colour safe is to disregard the Red channel altogether and replace it with a mixture of its Green and Blue elements put together and fed back into its Red component.
The problem is it doesn’t actually deal with the colour Red and pure Red can appear Black.
See? No?
So here’s the solution, and of course it’s more complicated.
Solution
Basically the full colour image has its Red, Green and Blue information multiplied and combined 3 times.
Here’s the blend file for the Retinal Rivalry thing available here.
