Uskian Chromatics

In his quest for a flexible and elementary magic usable by anybody, one approach the magician Uskius settled on was color. The method yielded access to subtle differentiation in elements, and its evocation was broadened to encompass differences in Weave contact, as well. Eventually, though, Uskius turned his attention to exploring other schools of metamagic, leaving the full mastery of the spell unrevealed.

With a gallant flourish you call forth your chosen color, which springs to life and splashes over the scene.

Player Preparation
When casting the spell, you can use a spell slot expended for the spell to choose up to spell slot level colors. At first level, these are the Primary Colors: Red, Blue, and Yellow. At second level, when you choose two primary colors they mix, forming a Secondary Color: Purple, Green, and Orange. At third level, you can mix all of the Primary Colors to form Brown, White, or Black.

Additionally, you gain proficiency Spectrum Points to change the Saturation and/or Luminosity of the color. Maximum Luminosity changes the spell's associated element and color to Radiant and White, and minimum Luminosity to Necrotic and Black, though other related effects to not change. At third level you can choose for the color to be White or Black and use Spectrum Points for other changes. It takes two Spectrum points to change to Maximum or Minimum Luminosity.
