Because of the nature of dice there can be some variation, the layers might not be as evenly dispersed, or the enamel paint blends in different unique ways. Here is a note from Little Dragon:
"I once flew into a fire; its light was dancing and vigorous. Such a voracious appetite, consuming everything in its way; then I saw him, a slender elemental, he had bits of wood he was shoving quickly into his mouth. Delight filled his features as he ate everything, he quickly looked at me as if I was food and I had to back away as fast as I could. He was so dangerous, everything was something that could be consumed, but the heat made my nights safer from the other creatures."
