## What is Hueful?

Hueful is a fast, beautiful contrast checker for designers and developers who care about accessible color. Verify any foreground/background pair against WCAG 2.1 and APCA, preview how your colors look to people with color vision deficiencies, and fix failing combinations in a single tap — all completely offline.

No account. No network. No tracking. Just the tools you need to ship color everyone can read.


WCAG 2.1 CONTRAST, AT A GLANCE
• Instant contrast ratio for any color pair
• Five-tier pass/fail badges: AA Normal, AA Large, AAA Normal, AAA Large, and UI Components
• Live type samples so you can see contrast at real text sizes
• Suggested Fix: tap to get the nearest passing color, found via perceptual LCh search

APCA (Lc) PERCEPTUAL CONTRAST
• APCA lightness contrast with polarity, shown alongside WCAG 2.1
• Font-tier guidance for body, fluent, spot, and large text
• Based on the perceptual model proposed in the WCAG 3 drafts

COLOR VISION SIMULATION
• Preview your colors through Protanopia, Deuteranopia, Tritanopia, and Achromatopsia
• Original and simulated views shown side by side
• Make sure your UI works for everyone, not just trichromatic vision

PICK COLORS FROM PHOTOS
• Eyedropper samples any color straight from a photo
• Runs on-device through the system photo picker — no library permission, no upload

WORK WITH WHOLE PALETTES
• Save and organize your color palettes
• Batch N×N contrast matrix checks every color against every other at once
• Spot every failing combination across an entire color system in seconds

EXPORT IN YOUR FORMAT
• Share a palette as an image
• Copy colors as Swift, SwiftUI, CSS, or JSON — ready to paste into your project

DESIGNED FOR iPHONE AND iPAD
• Native SwiftUI experience with full Dark Mode support
• Adaptive layout that expands to a roomy two-column view on larger screens
• Accessible, fast, and built to feel right at home on iOS

PRIVACY BY DESIGN
Hueful works entirely offline and collects no personal data. There are no analytics, no ads, no tracking, and no third-party SDKs. Palettes you create are stored only on your device and are shared only when you choose to. It even works in Airplane Mode.

Whether you're checking a single button label or auditing a whole design system, Hueful helps you get color contrast right — quickly, privately, and for free.
