So, here are the colors & their names. 22 in total:
Where did the color inspiration come from? retro My Little Ponies (generation 1)! Their mane colors, to be exact.
As in: the colors have been sampled from photos of MLP manes (both my own photos of my pony collection & ones found from the net).
Names of the colors were inspired by a website which sells hair for dolls and MLPs (no longer active?..).
Right now the palette is called 'Pony' or 'Pony colors' ...
I hope you like themm;;;
EDIT: some lovely people have turned these colors into Photoshop actions! For example, geirrendour made this set, thank you so much!
