Colored Skin

This was trained on over 150 images but some colors involved in training still need to have more samples for study. The weakest trained color in the mix is yellow it also doesn't help that it's close to a normal skin tone. Brown (as in art pallet brown not traditional skin tone) has minimal samples but seems to have been understood well. Pink and purple are dull and need to be revamped with darker colored characters to make a distinct difference. Any suggested characters or content for any of these colors is appreciated.
All colors included are:
-black
-green
-blue
-white
-grey

-red
