Reanimate.ColorComponents

Colors are three dimensional and can be projected into many color spaces with different properties.

Interpolating directly in the RGB color space is unintuitive and rarely useful. If you want to transition through color, you most likely want either the XYZ space (for physically accurate color transitions) or the LAB space (for esthetically pleasing colors).
