Gamut is a native X11 color-engineering tool for Linux. It provides a precision color picker, a multi-model harmony generator, a gradient builder with perceptual interpolation, a full-screen measurement overlay, and a live web-design preview — all in a single compact application built without GTK, Qt, or any large widget toolkit. Everything is built on Xtk, a self-contained C17 Xlib widget library written for this project, with LCMS2 for ICC-accurate conversions and WPEWebKit 2 for the embedded browser.
