Kromameter

Kromameter turns any image into powerful color intelligence.
100% on-device, no data collected.

Built for designers, developers, and anyone who cares about color, it analyzes images and transforms them into detailed palettes, harmonies, and accessibility insights you can actually use.

• Extract Colors Instantly
Drop an image into Kromameter and it analyzes up to 50,000 pixels to build a rich, accurate palette. The app identifies the colors that truly define your image and organizes them for easy exploration.
Supports PNG, JPEG, HEIC, TIFF, WebP, PSD, PDF, and GIF.

• Explore Your Palette
The Overview dashboard reveals the color story of your image. See dominant colors, coverage percentages, and a full breakdown of the hues detected in the analysis.
The All Colors view lets you explore every clustered color individually and copy any color instantly.

• Generate Beautiful Palettes
Kromameter automatically generates small, medium, and large palettes from your image. It also creates harmony based palettes using complementary, triadic, and analogous relationships.
Need full control? The Custom Palette Builder allows you to pick any combination of extracted colors and copy them together in one tap.

• Understand Color Harmony
The Harmony view places your colors on an interactive color wheel and generates balanced color sets based on color theory.
Explore complementary, analogous, triadic, tetradic, split complementary, and more.
A visual overview grid lets you compare every harmony at a glance.

• Check Accessibility Contrast
The built in Contrast Checker measures WCAG contrast ratios between any two colors from your palette. This makes it easy to design interfaces that remain readable and accessible.

• Simulate Color Blindness
Preview how your palette appears across eight different vision types including Deuteranopia, Protanopia, Tritanopia, Achromatopsia, and more.
Compare original and simulated colors side by side or review all vision types in a single overview to catch accessibility issues early.

• Export Anywhere
Bring your palette directly into your workflow with eleven export formats including SwiftUI, CSS, JSON, XML, and design token formats.
Export formats include:

SwiftUI and UIKit or AppKit

CSS Variables and SCSS

Copy colors instantly or save files directly on Mac.
