Peridot has lime-green skin and pale chartreuse yellow hair styled into a tetrahedron shape. When she blushes, it is green. Her true eye color is dark green, which is usually tinted by the yellow color of her visor. Her visor works similar to Garnet's, it being a part of her form yet not molded to her body.

Peridot formerly prioritized logic, reason, and objectivity above emotions. She was standing behind you, looking at you..
