Hypomelanistic
A variant of Brazilian Rainbow Boa (Epicrates cenchria)

Representative Brazilian Rainbow Boaphoto — a dedicated image of this exact morph isn't available yet.
A co-dominant trait reducing black pigment so the red/orange base glows more vividly and the rings appear lighter. Enhances the already-spectacular iridescence.
Keeper tips for this variant
Hypo is a healthy co-dominant gene, but the strict humidity demands of the species still apply fully — color won't compensate for husbandry, so hold the 80%+ humidity regardless.
