On Mendelian ratios alone...
Red flesh is going to be your dominant trait in the f2 and should be doing its thing in about 3/4 of your 50 F2's (37.5). 1/4 of those would be gf/gf so a black (purple or brown depending on skin color) (9.375). Subtract the blacks from the red fleshed and you get 28 red or pink, 9 purple or brown.
The remaining 12.5 are either yellow/white or gwr (again 1/4 of the 12 or 13).

So by Mendelian reckoning I get 3 green, 10 yellow or white, 9 purple or brown, 28 red or pink.
I could be wrong.
