  "description": "IBM (International Business Machines) is the company behind the Carbon Design System — the open-source design system that backs IBM's enterprise software surfaces (Cloud, watsonx, Db2, MQ, Power, Z, Storage, the consulting practice, and ibm.com). Carbon is built on a four-theme model: \"White\" and \"g10\" are the light themes, \"g90\" and \"g100\" are the dark themes. The primary interactive color is Blue 60 (#0F62FE) across every theme; semantic tokens map to Red 60 (danger), Green 50 (success), and Yellow 30 (warning). Typography is the proprietary IBM Plex family — Plex Sans, Plex Serif, and Plex Mono — released open-source under the SIL Open Font License and already present in this catalogue.\n",

Carbon is the authoritative published color system for the IBM brand on digital surfaces; the brand atom adds the IBM-specific typography references and the trademark / logo-usage rules Carbon does not itself encode. The g100 theme (dark mode) documented in the Carbon source uses gray-100 as the canvas and Blue 60 as the unchanged interactive color.\n"
