This LoRA aims to help with generating tanned or dark-skinned characters; in particular the hands and feet. In real life the palms and soles are lighter than the rest of the body due to a lack of melanin, but this isn't often reflected in artwork.

To use this LoRA simply use the tag "lssoles" for the soles of the feet and "lspalms" for the palms of the hands. Next, specify whether the character is dark-skinned or tanned by using the tags "dark skin" or "tanlines"; you may also add the type of tan for more accuracy.

Trigger: lssoles, lspalms

Type: dark skin OR tanlines
