For some items, like drones, Kath, and the groan tube, you can customize its color(s) in the menu. This could be expanded and added to avatars to allow for avatar customizations, such as outfits and color changes, to be moved outside of the parameters and expression menu system, to de-bloat those and have avatars load faster (in particular, bypassing the network parameter sync phase after an avatar loads by having those sent earlier).

Ideally, this system would let us set up a list of settings, including toggles, drop-downs, sliders, image grids (similar in function to drop-downs; probably as a subpage), and (perhaps most importantly) color pickers. Applying the changes there would probably reload the avatar with the new settings.

Nice-to-have as well: this could, for instance, render color-shifted textures to allow for efficient color changing on Quest, or allow for better outfit switching (i.e. by binding a GameObject to a setting, so that it's deleted entirely, or only loaded in the first place, if a certain value is set). Not everything has to be reloaded.
