wavelegnth absorbtion

what color absorbs 532 nm wavelegnths the best? besides black

Dark brown?

I think red ..... usually the color that adsorb better a wavelenght is the complementar color of the wavelenght itself.

The color we see is dependent on the reflective spectrum, not the absorption spectrum. A substance that absorbs green may or may not reflect red more than other colors. In general his tends to be substances that reflect red. However, whether or not a material absorbs a specific wavelength depends completely on the absorption spectrum, NOT the reflective spectrum (although the two are related).
