Color Editor

Browse for colors, pick them precisely, keep the keepers, derive shades and harmonies — and ship the set as a plain colors.css of named variables.

Features

A workbench, not a wizard.

Discover

Browse until something clicks

Space mints a calm random color, full-bleed. Step back through your history, or type a hex to see it large. Save the keepers.

Picker

A plane and a hue

A saturation/brightness plane with a hue slider and a synced hex field. Drag until it's right, then save the keeper.

Shades

Tints up, shades down

Pick a saved color and see it mid-ramp — lighter above, darker below, stepped in OKLCH so the spacing is perceptually even. Click a bar to keep it.

Wheel

Twelve hues, one mood

A donut wheel of twelve hues at your color's lightness and chroma. Same calm, different corner of the wheel. Click a wedge to keep it.

colors.css

The .css is the document

Name your keepers — --accent, --brand-500, anything — and save a plain :root block of custom properties. Opens and round-trips like any file.

Native Linux

Small binary, AppImage and .deb, real .css file association, in-app updater. No Electron.

Krill principles

A simple interface.

Focus One app, one job. One file, one window. No tabs, no project trees, no mode pickers — the work in front of you is the work.

Beauty A locked palette, careful typography, chrome that sits still. The apps shouldn't be the part of your desktop you have to forgive.

Simplicity No settings panel, no plugin system, no power-user knobs. If a feature can't be explained in a sentence, it doesn't ship.

Ownership Your files on your disk in their original format. No accounts, no cloud, no telemetry. MIT licensed; build it yourself if you don't trust ours.

Install

Quick install

One-liner — downloads the AppImage to ~/.local/bin, marks it executable, and registers a launcher entry. Re-run to upgrade.
