When dollers create their dolls or doll bases they often have their own group of usually three to five colours, which they regard as their own and to copy them is regarded as being unethical.
I have created a custom skin tone palette which have many graduated skin tones from which to choose.
There are also some tones for eyes and lip colours included in the palette as well.
Please feel free to fave or download this skin tone palette and use as a reference for creating your own small group of flesh tones for your dolls or doll bases.
If you wish to credit the palette, feel free but I do not require it for your use.
