Multiple color palettes for gear.
I'm not sure the term palette is correct.
I think it would be great if you could put multiple colors on gear. For example the new cloud outfit. It has parts which stay the same color, specifically the giant tarp connected to the chest piece. I think there should be a second dye slot where you could dye the secondary pieces/colored spots.
Other items include everything from the stripes on the "Striped velveteen Slops" to the red parts of the Sol gear.
This would allow more personalized customization of items, and just generally allow a wider variety in look, even if wearing the same gear pieces.
