About
Gamut captures colour from the world, checks it, and ships it in the format your work needs.
It's not another colour grabber. Capture is the easy part - Gamut makes the two things most colour apps treat as afterthoughts first-class: getting colour out in developer-grade formats, and keeping it accessible.
Capture
• Sample from the live camera with a magnified loupe - lock exposure and white balance so the colour is accurate, not whatever auto-exposure guessed.
• Eyedrop any pixel from a photo, in its true colour space.
• Enter colour by hex, RGB, HSL, or HSB. Pull several colours from one scene at once.
• Wide-gamut aware: Display P3 colours are captured and kept as P3, never flattened.
Organise
• Build palettes, name and reorder swatches, add notes and tags.
• Generate a harmony or a tonal ramp from any colour - complementary, analogous, triadic, split-complementary, tetradic, or a full tonal scale (Pro).
• Your library syncs across your devices through your own private iCloud (Pro).
Check (accessibility, first-class)
• WCAG contrast between any two colours - AA / AAA, normal / large text / UI components - with a plain verdict: "6.06:1 - passes AA, fails AAA."
• Tap a failing check to see the nearest colour that passes, with the ratio it reaches and how far it moved (Pro).
• Simulate colour-vision deficiency across the common types, on a swatch or a whole palette (Pro).
• Audit a palette for accessible pairings at a glance (Pro).
Export (the payoff)
• Per-swatch copy and per-palette export to the formats you actually build in: hex lists, CSS custom properties, OKLCH, SwiftUI Color + asset catalog, Tailwind config, JSON, and swatch PNGs.
• Export in sRGB or Display P3; out-of-gamut colours are surfaced, never silently clamped.
Native, fast, and calm. One job, done with care.
Gamut Pro unlocks iCloud sync, the accessibility tools, colour generation and contrast correction, the full export set, an unlimited library, and the Home-Screen palette widget. Available as a subscription or a one-time purchase.

What's New in Gamut
1.1.0
August 18, 2026
Generate a harmony or a tonal ramp from any colour in your library - complementary, analogous, triadic, split-complementary, tetradic, or a full tonal scale. Tap a failing contrast check to see the nearest colour that passes, with the ratio it reaches and how far it moved. OKLCH joins the per-colour value list and the export formats. Text now scales properly at the largest accessibility sizes across the app.
