It is not possible for for chimera to set the RGB frequencies, those are
determined by your display. But there are several things that can be
done to reduce and/or eliminate the ghosting you see:
1. Don't use any saturated colors: you'll get the best effect with
2. Get better red-cyan glasses: In general, paper glasses are
blurry compared to plastic glasses. But some plastic glasses do a
better job than others -- you'll need to do some research.
3. Reduce the amount of parallax in the image -- have (most)
everything behind the focal plane. Reducing the eye separation might
4. Not likely, but you might need to turn off any color correction
that your display is doing. Chimera does not use any color management,
so an image in just the red channel should only be shown with the
display's red light, but is possible that your display or operating
system is remapping the colors to match a particular ICC color profile,
e.g., the sRGB profile, and that might cause ghosting. The effect
should be too small to notice though.
P.S. Researching this I came across magenta-green stereo which is
supposed to be better than red-cyan stereo. Since you can buy
magenta-green glasses, I will add support into the daily build. Note
that magneta-green are right-left colors, unlike red-cyan which are
