(Mind Conquest) Protagonist Skin effect (Patreon)

So, I am working on designing the body for the protagonist of Mind Conquest, so that you can switch into that body when it is healed fully. (It will be possible to instead remain in Terri's body if you prefer it.) Most of the character's design is fire themed, with fiery hair that starts black then turns red towards the tips, a red cape, and a red flame that channels down their right arm.

What I am uncertain of, however, is the skin. Whether it would look better for the protagonist to have ash-gray skin, or burnt black skin; or to have one for their male form and the other for their female form. 

So, I thought I would go ahead and ask you guys which you would prefer.
