Tiefling Paladin characters

Tiefling paladins here are deep crimson or burgundy almost to a person, and the armour is what tells them apart. Darkened steel engraved with celestial symbols, polished steel with ornate white detail and a gilded longsword, plain gleaming plate. Horns are dark and curled, one pair ash grey. Hair goes white or silver more than you'd expect, snow-white curls on one and thick silver waves on another, which looks good against red skin. Eyes are gold. One is done as an oil painting. The contrast between an infernal face and holy armour is the whole idea, so lean into it.
