## What is Color Contrast & Palette?

Build color schemes people can actually read. Lift a color straight out of a photo, get twelve matching shades that pass, and preview your real text on top.

Color Contrast & Palette is the essential tool for designers and developers who care about accessibility. Whether you're building a brand new interface or auditing an existing design, this app helps you ensure every color combination meets the highest accessibility standards.

KEY FEATURES

- Real-Time Contrast Ratio Calculation
Enter any two colors and instantly see the contrast ratio. Results update in real time as you adjust your palette.

- WCAG AA & AAA Validation
Check your color pairs against both AA and AAA compliance levels for normal text, large text, and UI components.

- Smart Color Suggestions
When a color combination falls short, get intelligent suggestions for accessible alternatives that stay close to your original palette.

- Eyedropper: Sample a Color from a Photo
Tap anywhere in a photo — a wall, a logo, a product shot — and the exact color of that pixel becomes your text or background color. Works with your photo library or the camera.

- Visual Preview
See how your text and background combinations actually look with a live preview, so you can make informed design decisions at a glance.

- Save Your Favorite Combinations
Give a color pair a name and keep it. Saved combinations come back with a single tap, ready for the next screen you design.

BUILT FOR DESIGNERS

Color Contrast & Palette was created with design professionals in mind. The clean, focused interface lets you work quickly without distractions. Whether you're a UI designer, front-end developer, or accessibility consultant, this tool fits naturally into your workflow.

WCAG 2.0 STANDARDS

The Web Content Accessibility Guidelines (WCAG) define minimum contrast ratios to ensure content is readable for people with visual impairments. Color Contrast & Palette makes it effortless to verify compliance, helping you build inclusive digital experiences.
