Help, Stain from Betadine Bath. Will it go away?

Hi, I have a hatchling palmetto corn snake who's tip of his tail has a bit of tail rot. And I did research that a short soak in a Betadine solution 2-3 times a day, and then some Neosporin can help treat it while I'm waiting to get into a vet. (Vets are booked out 2-3 weeks where I live). I soaked him in a Betadine solution that was I'd say 1 part betadine to 5 parts water. And I let him soak in that for about 5 minutes I'd say. And now he's a yellow snake.... And I'm sure you all know how beautifully white Palmetto's are supposed to be. I'm really scared that this stain is permanent. He just shed yesterday, which is when I noticed the tail rot.

If he's just going to be yellow until his next shed, I can live with that, but if I've permanently stained him.... I'll be devastated.

Continuing his treatment, I won't be giving him full body soaks anymore. I'll do my best to just dip his tail in, but with how squirmy corn snakes are, that'll be hard, which is why I opted for the full bath this first time..... Sigh.

Although I haven't done betadine with a white snake, I feel like it's very likely that it will be completely gone by the next shed.

I also imagine it would disappear with the next shed.
