One of my best students asked ths. We had been discussing absorption and 
action spectra - chlorophylls a, b etc and she suggested that black 
pignments would absorb the green wavelengths and allow plants more energy 
for growth etc. I thought it might make plants too hot, but I was just 
guessing !
