In fact... leaves are not reflecting green... they are reflecting light which YOU
perceive 
as green.

Not the same thing.
Take any satellite view in IR or UV, and you will see (in false colors) that all
plants 
are not the same "green" (as well as providing information about water-need, it's also

changing from species to species: some smart agency detects drugs-fields that way).

As leaves in autumns show, they have various pigments to react with the light.
Chlorophyll (the whole family) works less with green. Hence the green of leaves.
But in the family, some are more efficient on different red/IR/blue/UV.
