I can see how you might think that, since "red" colored plants reflect red light and to our eyes not so much green, but that's not the case. Chlorophyll can't change its absorption spectrum according to what plant it is in. Plants may have a different ratio of chlorophyll A to chlorophyll B. (Each chlorophyll has a slight difference in light wavelengths that it uses.) But they still reflect predominantly green in the spectrum that we see. So green light is a poor source of energy for any plant that uses chlorophyll.
We all learned why leaves change color in the fall, and that at least some of that fall color is present all summer long in leaves, only masked by the overwhelming presence of the green chlorophyll. It's the same with "red" plants. The chlorophyll is still there doing its job, but masked by the overwhelming red.
