I’ve been wanting to address this for a while. Note that I’m not an expert on this subject, since I do not use pre-set palettes and I am mostly a tool-shader.
But WHY does it matter so much? The dolls are obviously not going to look the same, it all depends on HOW you use it. Mariiii has proved this at her site, by shading a skirt with various styles to expose the fact that the same palette can have tons of diversity.
There are only so many colours, who cares if yours match somebody else’s?
