Yeah... It will be a great day when organics actually get an in-game function. But organics are not always green (the foliage and stuff). Here around our K type star, the leaves absorb the yellow, red and blue light (abundant wavelengths) and reflect the green (lower abundant wavelength). Perhaps around an M-dwarf (red dwarf), where there is more red and infrared light, the leaves could be blue or even black. Or around an O type star (not that that is really common or anything) the leaves might be red. The thing is, around such stars, eg, that O type, there isnt much red light to reflect in the first place, so the leaves might be yellow? I dont know, but you know that I know that it will be interesting to see this in action when life is added.
