[Eyes have a secondary set of colors they can swap between]
Eyes (cluster and/or true eyes) may have their base and pupil color shift between one other color to another set of colors.
Eyes with patterns, dual color, sectoral eye, etc. do not have their shape change but may have their color change along with the base color of the eye.
Effects on the eye such as sparkle, opalescent, or metallic do not change their effect but may change color with the eye.
Cannot stack for multiple colors or multiple variants of eyes. Only applies once to allow one additional set of colors on a singular eye set.
