On the front page i've listed Masks as not planned, including color masks, they would be a lot of work, i wouldn't know how to render them (not to mention it would require re-rendering every single frame again) and at the end they would look like a bad recolor considering that the Wicker was specifically made to be purple.
The armor on the other hand could be recolored (although it would be hardly visible). I'm also planning a new level 1 armor (an actual entire outfit) that could have multiple versions or colors but the main character simply won't look satisfying to just recolor. If anything i'd have to make a greyscale version (and tune that greyscale version to be colorable purple with the exact same outcome as it is now) and use that as base for recolors (stripes and eyes mainly come to mind as they offer the most logical recolor options).
Not sure if there would be an easy and cheap way of doing color masks that doesn't look bad.
