Yes, for red-cyan stereo, chimera puts the left eye in the red channel and
the right eye in the blue and green channels. This allows for stereo
viewing of color images with red-cyan glasses, but there are many
problems, such as red objects not having any stereo cues because they are
in only one eye. You will get the best stereo effect with gray-scale
images (shades of gray) and if you do use color, avoid saturated colors.
You can see the red, green, and blue components of a color with chimera's
Color Editor tool. The color name field can be set to any of the color
names in the Actions Color menu.
Other glasses, red-blue and red-green, will work well with gray-scale
images, but will have greater problems with ghosting (ie., part of one
eye's image appearing in the other's) in color images. Ghosting will
always be present to some degree unless the glasses are perfectly matched
to the frequencies of light emitted by the display.
So the best advice is to color your data various shades of gray.
Hope this helps,
