    It has to do with the ligh absorbed by the chlorophylls and other pigments (which is not green).



    The green light is around 550 nm wavelength.

    Chlorophyll is a complex biomolecule containing magnesium. The molecule contains
    special ring shaped structures that capture preferred wavelengths of light. Green is not "captured" so it is reflected back to our eye. I do know that plants may contain modified chlorophyll and other pigments to take advantage of the type of light available to them.
    @jazzy07 Your other posts on this forum have been deleted for two reasons. The first is that at least one was a bump saying, "cool post" (I paraphrase). The other is that the post quoted above is a direct copy/paste of another site as are several others.

    Nothing is certain, but uncertainty.

    Some bacteriochlorophyll is purple/brownish. As far as I know though, chlorophyll a and b are the only ones found in plants, and chlorophyll d found in cyanobacteria is green as well.

    There are plants that aren't green but this isn't due to a difference in their chlorophyl, it's the effect of other pigments present (Different plants will have different levels of carotenoids, like beta-carotene that can have a huge effect on the colour). Or, in some cases parasitic plants have almost no pigment at all.
