Make accessible app color palettes without the tedium of manual testing.

Your edits get WCAG color contrast tested instantly with simulated color blindness (Machado et al). Transparency is layered for you. Tests appear in summarized grids by appearance (e.g., dark or Apple TV). Drill-down to solve problems or get suggested fixes.

UI mockups  — More easily find that text–background combos and visualize chart colors
Batch edits  — Apply similar changes to multiple colors (e.g., invert, desaturate 10%)
Import/export  — Xcode asset catalogs, Swift, hex, raw triplets, macOS color lists, or use a batch mouse picker
Peer-reviewed color maps  —  Nearly 70 accessible schemes by scientists for vary data types (e.g., cyclical)
Gradient builder  — Generate smooth color ramps using color theory and a perceptual color space
Snapshots  — See before/afters or create branches in your document

What’s WCAG?  — Apple recommends developers follow the Web Content Accessibility Guidelines for interfaces. A few requirements relate to ensuring text and meaningful UI elements are legible for people with low to moderate visual acuity or color blindness. To get a feel for WCAG’s definition of a contrast ratio, you might enjoy my other app, WCAG Shades, that strips your camera of any pixels failing a WCAG test.

Release notes:
Supports new system colors in iOS 15 and macOS 12
