I would have to look into it much further to truly help you with this particular problem, but I can say that usually you do not see red (or blue for that matter) when you do chromotraphy on leave pigments because those are the two colors that the pigments that carry out photosynthesis in leaves absorb the most.
For most NORMAL (i.e. green) leaves, when you seperate chorophyll, xanthophyll, etc. using chromotagraphy, you should get a whole lot of green and yellow staring back at you because those are the colors that are not being absorbed by that particular pigment (those are the colors being reflected back to your eye from each individual pigment). Of course, you have not been given a normal plant; so from that basic idea, you are going to have to modify and interpret what the differences could be between a green and red leaf (they don't call it "honors" for nothing
).
