can you add 1 dye, and then change it to another dye and then change again

I might wanna shift between exclusive pelts for my wolf Moonlight if possible

I believe you can the new dye will just replace the old one

I'm fairly certain you can. I've never tried it myself, but since base coats aren't technically "permanent" and can be changed by dyes, I'd think you could change the base coat as much as you want, permitted you have the dye you want to use.
