OpenAI Color Palette
Off-white, charcoal, and a single signature green for the most-talked-about AI brand.
OpenAI's brand expression centers on the spiral / hexagon mark in pure black on near-white, with the signature #10A37F green as the only chromatic accent — visible on the ChatGPT 'Send' button, on streaming-response indicators, and on the wordmark in some compositions. The restraint is deliberate; in a market full of neon-purple AI brands, OpenAI's near-monochrome reads as the steady incumbent.
