american toad changing color- green to red?

[dickwad666]

So from what I've gathered, color changes in american toads are totally normal, but I just want to make sure because red is a weird color for my little boy to turn!
I put some maple leaves I got from my backyard in the toad abode for a little fall-time enrichment, and I think that might be the reason for the change?
He spent the last couple days in his hide so I only noticed this today when he came out to hunt.
toadbert as his usual green self
he's got a little red spotting around his nose & up beside his eyes and 'sacks

I'm sure he's just fine cus he's eatin' and soakin' as usual no problems, but I just want to get a second opinion.
More importantly, I want to know if I keep adding maple leaves will he keep turning red? Because I want that to happen, he looks handsome.



PS: here he is in his halloween costume!
