Would it be possible to turn off the lighting effects, so that colours are not changed as the polyhedron rotates ? Being red-green colourblind, I see face colours apparently change (for example, from green to yellow) as I rotate the model. I do this so that I can determine the arrangement of colours around each vertex, but as the colours appear to change, I can easily lose track of where I am.

Alternatively, perhaps it might be possible to display numeric labels at each vertex ? Mind, you it would probably be easier for you (and better for me) just to print a report showing vertex colours.

I'm guessing that with no light source, things would get pretty black.

I'm also guessing that any polychromatic light source will have consequences for one form of colour-blindness or another.

How about an option for a monochromatic light source to match the raw pixels - choice of red, green or blue.

What I'm looking for is an option to maintain the same RGB values for all pixels as they move position. I don't think that this necessarily implies a monochromatic light source, but I'm no expert in this area. personally, I don't need to be able to look at a patch of colour and identify it correctly; I just don't want it to change due to shading.

Stella uses OpenGL (the Open Graphics Library) for rendering. AFAIK this is just like the real world in that it needs a light source or everything looks black. The 3D rotation, perspective and stuff is also handled by OpenGL, so decoupling the colour from the rest of the software might be a problem. At least, that's what I would expect.

The good thing about monochrome light is that the shade of colour would be constant, it would just get darker or lighter when lit from a different angle.
