Why is chlorophyll green? Isn't there a more energetically favorable color?

Chlorophyll being green mean is absorbs in the red area of the spectrum. Isn't this low energy light? Wouldn't plants get more energy if they absorbed light in the violet area of the spectrum?

Chlorophyll-a, the common green pigment you are referring to, isn't the only pigment in your average green leaf. There is also chlorophyll-b and the carotenoids, which broaden the light energies (colors) absorbed by the leaf. These are appparent during the fall as the leaves change color. Chlorophyll-a is important and most common because it doesn't only absorb energy, but it also facilitates the chemical reactions that allow the plant to use that energy.
