OpenAI's product surface reads like a research lab dressed for the public — clinical, restrained, deliberately quiet. The page background is a true white (`#ffffff`) layered against a near-black ink (`#0d0d0d`) with a subtle teal undertone, so even the text feels slightly cooled rather than aggressively dark. The result is a chromatic neutrality that puts model output, code, and prose front and center, not the chrome around them.
