I was reading their website the other day, and found their technical page:

http://chromatek.com/what-is-chromadepth/chromadepth-technical-explanation/

According to them, the glasses work on computer displays and printed 
materials too.

Quote: "On a black background, red will appear closest, blue furthest, 
and the other colors will fall in-between according to their place in 
the rainbow (red, orange, yellow, green, blue)."

So, any color should work okay, not just the primaries.
