The sun’s spectrum at the earth surface peaks in the green color range, which should make green the most efficient choice. Although, I wonder why they have to absorb only a single or a narrow band of color.

Producing multiple pigments to absorb more colours is very expensive, and the chemical reactions only take a certain amount of energy, anything beyond is converted into heat (which is bad for water retention).
