Every combination of anaglyph filter colors has certain advantages and disadvantages. While red-cyan is the de facto standard, other color combinations can display other ranges of colors. Most notably, the amber-blue combination can display a large range of colors. It was mostly used for ColorCode 3-D, which uses a proprietary algorithm to pre-process anaglyphs for better representation via their amber-blue glasses.
The naive approach of using the RG color channels for one eye and the B channel for the other eye might not be as good as ColorCode 3-D's implementation. However, there is another method described here and the Dubois filter could also be used according to the author. The matrix for the latter can be found here.
An example implementation of amber/blue with the Dubois filter can be found here.
I suggest to add at least an amber-blue anaglyphic mode for improved color perception.
