Not a rainbow incinerator I’ll attach what a rainbow incinerator looks like... there’s 2 strains of it but the other doesn’t look far off from the picture attached
So to me it looks like a Candy Apple variety/toucan Sam/Shazam type thing hard to say it’s definitely one of these because it doesn’t exactly match the known coloration which could be due to lighting but I’m leaning towards a Candy Apple variety.... attached is my friends zoas left is Candy Apple red and right is toucan Sam
