BIOLOGY HELP. What type of pigments are in this leaf?

Okay, so I have an assignment due tomorrow. On Friday we had an experiment where we put leaf pigment extract onto this paper, poured developing solution in a test tube. Put the paper in the test tube, but not so the leaf pigment could touch the developing solution. And then colors starting erupting from above where we had put the pigment extract.

The thing I need to find (and it has no reference to it in the book), is what colors are the different pigments in a leaf. Someone just direct me to a website showing different colors and labeling them. I have this faded yellow, faded kind of sea-green, olive green and then faded green.

PLEASE HELP!!

"Remove your chromatogram after 15 minutes. Let the paper strip dry in a well-ventilated area. Study your chromatogram and sketch the results. You should be able to identify the carotenoids (orange carotene and yellow xanthophyll) at the top. Chlorophyll a appears dark green and chlorophyll b appears light green. The pigments will fade in the light, so record your observations quickly"
