Color math stays local. Judgment stays human.

HEX/RGB/HSL, shades, WCAG contrast, and approximate color-vision previews are calculated in the current browser without uploading color values or reports.

Calculations and approximate models

Color conversion, relative luminance, contrast, and shades are calculated by page JavaScript. The color-vision preview applies approximate Protan-like, Deutan-like, and Tritan-like matrices in linear sRGB, then shows A/B labels, a distance heuristic, and text guidance. It is not a medical diagnosis, does not exactly represent anyone's vision, and is neither WCAG certification nor a substitute for testing with real users.

Workspace and copying

Only when you explicitly choose Save or Import are current form fields stored as a local workspace in this browser; you can export it as JSON, restore it from a local JSON file, or clear it at any time. Undo history stays only in the current tab. Copying a color value, swatch, or check report writes to the system clipboard only after a click; ColorStep does not read the clipboard. Copied or exported content is then controlled by the device and other apps.

Display preferences and ads

The site uses .miluland.com domain cookies to sync language, theme, high-contrast preference, and up to 16 favorite tool IDs across MiluLand sites, with a local compatibility copy on the current site. Favorites contain only tool IDs—never inputs, files, or results—and can be cleared from the MiluLand tool directory or browser settings.

This page uses Google AdSense Auto Ads. Third parties may process cookies and ordinary network information under their policies; ColorStep does not intentionally provide color values, model results, reports, or workspaces to the ad system.
