ive always wondered why leaves all generally evolved to be green instead of black. wouldnt black be more efficient?

The short answer is that absorbing a narrow band of energies is more efficient than a wide band.

Because other wavelengths were probably already taken. https://en.m.wikipedia.org/wiki/Purple_Earth_hypothesis (Black is not a wavelength but rather the absence of visible light, e. g. it has all been absorbed)
