This is obviously true for plants evolved on earth.
Chlorophyll (and other accessory photosynthetic active plant pigments) are not evolved to gather "green" wave lengths, as they are underrepresented in the spectrum of the sun and yield the least energy.
This might be completely different under alien suns with different spectrum:
Plants evolved on planets orbiting a red dwarf will probably appear completely black, as they need to gather each and every wave length they can "lay their chloroplasts on" (or whatever they use).
Plants, on the other hand, that evolved on planets under a white-blue sun might even need to reflect ultra violett wave lenths, as they would burn otherwise. Forests on these planets would sparkle in bright light, emitted from their leaves.

(Or won't have leaves at all, as a too big surface won't do any good (think kaktea in our deserts).)
Tl;dr: necessary wave lengths will differ for alien plants dependent to the sun they evolved under - and so does the light in space satations growing them.
