This is actually old wisdom, at least as to why plants are green. There was a discovery a couple years back that green light alone actually can cause water to evaporate well above the thermal limit. Since evolution is best modeled as an energy minimization problem, the fact that the least energy required to retain moisture is accomplished by being green is why chlorophyll is green.
