The Linux Foundation

The Linux Foundation brand palette is anchored on a deep corporate blue scale — LF Dark Blue (#003778), LF Darker Blue (#003764), and LF Bright Blue (#0094FF) — captured directly from the resolved fills of the official LF stacked-color logo distributed via linuxfoundation.org. The Foundation's brand voice is institutional and ecosystem-scaled: stewardship of Linux, Kubernetes, CNCF, OpenJS, and dozens of other industry-spanning open-source projects.

Notes
The Linux Foundation brand-guidelines page does not publish hex values in prose; the canonical values are the resolved fill colors in the official LF stacked-color SVG. The Foundation's brand expression is dark-blue-first on a white canvas; this palette also encodes a sensible dark-mode inversion (deep navy canvas, LF Bright Blue accent preserved).
