GitHub Color Palette
The Octocat is grayscale; the system colors carry semantic meaning.
GitHub's brand mark is intentionally monochrome, leaving the colorful semantic palette (success green, attention yellow, danger red, accent blue) to operate on top inside the product. This separation — neutral identity, vivid signal — is a useful pattern for any developer-facing tool.
