Eclipse Foundation

Eclipse Foundation brand palette anchored on Eclipse Orange (#F06C02) — the fill of the sun-arc element in the modern Eclipse Foundation logo — paired with a near-black wordmark on a clean white canvas. The Foundation stewards the Eclipse IDE, Jakarta EE, Adoptium (Temurin), Mosquitto, Vert.x, MicroProfile, and a broad portfolio of working groups spanning enterprise, embedded, and research open-source.

Notes
The Eclipse Foundation Logo Guidelines page documents the monochromatic, color, and reversed-color variants but does not publish hex values in prose. The #F06C02 orange is the resolved fill in the official "white-orange" Eclipse Foundation SVG (a confirming #F7941E orange also appears in the Solstice theme's warning-button CSS class on eclipse.org). The wordmark is rendered in black on a white canvas in the modern 2024-refresh expression; this palette encodes both the light-first surface and a sensible dark-mode inversion.
