Color, precisely.
A native macOS workspace for picking, converting, and building color systems. Always in your menu bar. Built for designers and developers who care about accuracy.

#6B20A4oklch(55% .26 287°)Screen loupe
Pick from anywhere
on your screen.
The built-in loupe captures every pixel using ScreenCaptureKit, tracks the display profile under your cursor, and converts sampled colors through ColorSync into your canonical working space — with HDR headroom preserved where the OS exposes it.
- Exact pixel & averaged region modes
- Freeze frame and keyboard nudge
- Multi-display aware, Retina-accurate
- 5-second menu-bar color flash on pick
Built for precision
Everything a color tool should do.
Avocolor handles every detail between the pixel you pick and the format you ship — without losing accuracy along the way.
Every format you need
Copy as hex, CSS rgb/hsl/oklch/color(), SwiftUI Color, NSColor, UIColor, Android XML, Jetpack Compose, Figma design tokens, and JSON. Format history and last-used preference included.
Contrast & accessibility
WCAG 2 ratios with pass/fail labels for normal text, large text, and UI components. Contrast suggestions preserve your hue while adjusting lightness and chroma to the nearest accessible variant.
Wide gamut & HDR
First-class support for Display P3, Rec.2020, and linear RGB. Out-of-sRGB-gamut colors are flagged, never silently clipped. HDR headroom is preserved when sampling from extended-range displays.
OKLab perceptual engine
All scale generation, harmony variants, and lightness adjustments operate in OKLab/OKLCH — the most perceptually uniform color space available. Physical compositing uses linear RGB. Nothing approximates.
Materials library
Define materials with base color, surface role, semantic role, light/dark variants, and platform target. Export to SwiftUI, AppKit, Android, or web design tokens directly from your material library.
Local-first storage
Colors, palettes, and libraries are stored locally in SQLite via GRDB. Everything survives relaunch, exports to JSON, and imports back. iCloud sync hooks are in place for a future update.
Scale generator
Perceptual scales,
not math scales.
Avocolor interpolates in OKLab so every step looks evenly spaced to human eyes — no more muddy mid-tones or washed-out highlights from linear RGB interpolation.
- Adjustable step count
- Lightness, chroma, and hue interpolation
- Target gamut overlay
- Easing curves and custom bezier editor (coming)
- Contrast-aware validation
- Export to Tailwind, CSS, Figma, or tokens
Every scale is generated in OKLab, then optionally clipped to your target gamut (sRGB, Display P3, or Rec.2020). Out-of-gamut steps are flagged, never silently mapped.
Built-in libraries

Full default palette — all 22 hues × 11 steps.
Radix Colors
28 accessible color scales with P3 wide-gamut variants.
Apple System
macOS / iOS system colors, semantic roles, and fills.

Trusted by designers
and engineers.
“I've used every macOS color picker. Avocolor is the only one that doesn't lie to me about wide-gamut colors. The OKLCH picker alone made it worth switching.”
“The contrast checker with OKLCH-aware suggestions saved me hours on our design system audit. It adjusts lightness without touching the hue — exactly what I wanted.”
“As an iOS developer, having SwiftUI color output that correctly references the display profile — not just a rounded hex — is genuinely rare. Avocolor gets it right.”
