Couleurs is a native Mac color-picker utility that lets you sample any pixel on your display and immediately refine, copy, or export that color in whatever format your workflow demands.
What is Couleurs?
Couleurs is a lightweight macOS app built around one tightly scoped job: reach anywhere on your screen, pluck a color, and hand it to you in a usable form. Unlike the system Digital Color Meter, which reads values but offers no editing path, Couleurs pairs the eyedropper with a small but surprisingly capable inspector that lets you push the hue, tweak saturation, or dial in lightness before you ever paste the value into your code or design file.
The workflow is deliberately minimal. Invoke the picker with a global shortcut, hover over any pixel — a browser window, a PDF, a photo open in Preview — and click. The color lands in Couleurs' history list, timestamped and ready. From there you can copy it as a hex string, an RGB triplet, HSL values, or an NSColor literal. For developers who bounce between Figma, Xcode, and a CSS file in the same afternoon, that format flexibility alone is worth the install.
What does Couleurs do best?
Couleurs excels at getting out of your way. The magnified loupe gives you per-pixel precision on Retina displays without requiring you to zoom the source content first — something Digital Color Meter handles clumsily and most browser DevTools color pickers cannot do at all.
A few things I use constantly:
- Persistent history — sampled colors stack up in a scrollable list, so picking a palette from a reference screenshot is a ten-second job, not a clipboard juggling act.
- Live adjustment — once a color is captured, the HSL/RGB sliders let you nudge it toward your brand token without firing up Photoshop.
- One-click copy in the right format — switching between hex for CSS and NSColor for Swift is a single tap, not a mental-math conversion.
- Menu-bar presence — Couleurs lives quietly in the menu bar; there is no Dock icon crowding your taskbar.
Is Couleurs free?
Couleurs is free to download. The developer distributes it directly from the official site and through Homebrew Cask, with no mandatory account or paywall blocking the core pick-and-copy loop. Check the official site for any optional tip-jar or upgrade tier, as pricing details can change between releases.
Who should use Couleurs?
If you spend meaningful time in front of Figma, Sketch, Xcode, or a code editor and regularly need to match colors from mockups, brand guides, or existing interfaces, Couleurs is built precisely for you. It is especially useful for indie developers doing their own UI polish — the kind of person who does not want to open a full design tool just to identify what shade of gray Apple uses in its sidebar.
Graphic designers who already live inside Figma or Affinity Designer may find those apps' built-in pickers sufficient. And if your color work is confined entirely to the browser, DevTools' eyedropper covers the basics. But anyone who needs to hop between multiple apps — a renderer in one window, Xcode in another, a spec PDF in a third — will appreciate having a dedicated system-wide tool that operates above every window without interfering with any of them.
How does Couleurs compare to alternatives?
The closest free competitor is Apple's own Digital Color Meter, which ships with macOS. It reads colors accurately but provides no history, no adjustment controls, and no format switching — you get a readout and nothing more. Pastel and Sip are the two commercial options most designers compare Couleurs against. Sip is the most feature-rich of the three, offering palette organisation, team sync, and integrations with design tools, but it costs more and carries a subscription. Pastel sits in the middle — polished palette management, pleasant UI, no subscription — but its eyedropper is secondary to its organisational features. Couleurs is the leanest and fastest of the bunch; it wins when you want a capture-and-copy reflex, not a palette management system.
For power-users deep in color system work — maintaining a design token library across multiple brands — Sip or Pastel probably serve you better. For everyone else, Couleurs' focused scope is a virtue, not a limitation.
What are the best Couleurs alternatives?
The main alternatives worth evaluating are Sip (richest feature set, subscription pricing), Pastel (palette-first, one-time purchase), and Digital Color Meter (free, Apple-native, no frills). For in-browser work, Chrome and Firefox DevTools both include inline pickers. If you want something closer to Couleurs' lightweight philosophy, ColorSnapper 2 is another solid single-purchase option worth a look.
Does Couleurs support Apple Silicon?
Couleurs is a native macOS app actively maintained by its developer, and it runs natively on Apple Silicon Macs. Performance on M-series hardware is snappy — the magnified loupe tracks the cursor without any perceptible lag, even on high-refresh displays.
