A gift purported by the Chromeria to only by possessed by the Prism. It seems to have two parts.
First, the Lightsplitter is able to draft luxin of a specific color by splitting the light internally into its constituent wavelengths. But this only applies if they are a drafter as well as a lightsplitter. The Prism is the only known example.
Second, the lightsplitter can absorb all light of a certain wavelength(s), and diffuse it through other parts of the spectrum. So far, this has only been used for invisibility, but theoretically it could be used to change any wavelength of light into any other.
