Helps get Heterochromia, you can define which eye is which colour and follows pretty accurately.

Example : Heterochromia, left eye yellow, right eye red 

Only requires heterochromia as a trigger and will randomly choose a colour,

favours blues reds and greens. Works well with weight 0.7-0.9

Version 2 of my Heterochromia LoRA.

100 images, higher resolution more variety of colors. Still only trigger required is Heterochromia, using only the trigger will provide a random set of colors.

It favors reds and yellows if left to it's own devices.

It recognizes specific colors such as "Left eye yellow, right eye blue", though sometimes it gets it's left and right confused, you'll typically get the results you're looking for.

A Fun side effect of me adding more colors to the mix was a nifty rainbow eye. I have yet to reproduce it by prompt, however you might get lucky. Occasionally produces reflections and artefacts within the iris, comes off looking a bit reflective
