Locking in fur color and shade

Can anybody help me with this? I’m trying to get AI to be consistent about a shade of fur like the image below, but I can’t seem to get a stick… it’s regularly either ignoring the color I told it to use and using the Canon fur color, or misinterpreting dark fur as black clothes instead.

I think super dark fur colors are a weakness of PDXL (not many characters have dark-colored coats outside of earthen tones, so it’s not surprising). I usually have to manually paint in the desired color and do a denoise for darker coats that aren’t canon characters.
