Sorry for the delay I'm still playing with it but I figured I would come back and put the triggers.
The LoRA was trained to generate the following colors. I do worry it may have lost some adherence due to how many different concepts I trained.
Trigger words-
g41xy- Galaxy hair: gradient color palette including blues, purples and pinks
sun53t- Sunset hair: gradient color palette with reds oranges and purples
f1re- Flame hair: gradient color palette with reds orange and yellows
M3rm- Mermaid hair: gradient color palette with aquas, mints, pinks and purples.
H0lg- Holographic hair: mostly blonde or white with rainbow prism effect
P1nk- Pink hair: a variety of two toned pinks
R0se- Rose gold hair
b1ue- Blue hair
Gr33n- Green hair
