Some equipments has a blackish or dark base color, so even if the color is changed, the appearance of the equipment remains almost the same.
Therefore, it would be better to be able to change from the base color, but is this possible?
One more thing.
Colorings can be made in two places, the main color and the secondary color, but some items have colorings that can be made in parts where it is not clear at all which color has been changed, such as the small decorative rings on gauntlets or the heels on greaves.
This also should be able to change the color of the main part of the equipment (the prominent part).
That's all.
