  "description": "Roblox is the San Mateo-headquartered user-generated-content gaming platform — covering the Roblox client across PC, mobile, Xbox, PlayStation, and Meta Quest; the Roblox Studio creator IDE; the Robux virtual currency and Marketplace; and the hundreds of millions of player-created \"experiences\" hosted on the platform. The brand voice under the recent \"Foundation\" design-system rebrand is platform-confident and creator-first: the chrome carries the developer / creator surfaces while the in-experience artwork inside individual games provides chromatic variety. Visually, Roblox is dual-mode with a strong dark-mode default on the consumer site: a deep ink canvas (#121215 / #191A1F) carries the page chrome, with the \"System Emphasis\" blue (#335FFF) as the calibrated primary action across both modes. The earlier red-orange Roblox identity has been retired under Foundation in favor of this blue-centered palette.\nTypography is the proprietary Builder Sans family.\n",
