Can I force cam.3d2d to consider lighting?

For the context: I making Bulletin Boards Addon and want to render notes with colors dependend on light.

By standard cam.* library renders colors in full bright. I could go the lazy way and use a texture (for paper) and slap black text onto it, but is there a way to make the way I intend work?

Also I'm in process of reading book and learning about 3d math for game dev/graphics dev so any additional sources that could help me understand the concepts better would be nice :D
