    Style LoRA trained on Commodore 64 "Petscii" art.

    Training images were converted to use the RGB colors from this GIMP palette:

    https://github.com/denilsonsa/gimp-palettes/blob/master/palettes/HW-Commodore-64.gpl

    Color accuracy isn't perfect, the model will sometimes add extra shades.

    Artist tags can improve composition but may affect color accuracy.
