On the contrary, the chlorophyl molecule readily absorbs red/orange light leaving the blues and greens to be reflected hence, giving most plants their green color. Green food coloring does the same thing for the same reason. All dyes and pigments are based on molecules that absorb different frequencies of light. Those frequencies that are absorbed, correspond to energy levels of the molecules that make up the dyes. The other frequencies are left alone and combine to make the "color" of the object.
