  "description": "The Massachusetts Institute of Technology — the research university whose institutional identity rests on three core colours (MIT Red, Silver Gray, Bright Red) plus black and white. MIT's brand voice is direct, technical, and confident: rigorous typography, restrained colour, and a deliberate refusal of decorative treatment on the seal and wordmark. The expanded palette adds high-chroma pinks, purples, blues, greens, and a yellow that MIT pairs with the core for editorial and digital surfaces while keeping MIT Red as the institutional anchor.\n",
