The Chromatic Collection is a big set of textures that allows you to make the combination of colours you want in game. It’s basically a DIY hair colours.
Since September 2020, all my Patreon hairstyles use this big set of textures, and they all come with special editions of the hairs such as bicolour and chunky, and more colour options for the base hairs, like roots and ombrè fades.
You can download the textures from this direct link, but if you want to learn more about it or download more awesome things check out my Patreon!
