⚡ Contrast Accessibility (WCAG 2.1)
Frequently Asked Questions
Yes, completely free. No signup required, no usage limits, and no watermarks. Upload as many images as you want and extract unlimited color palettes.
No. All image processing happens locally in your browser using the HTML5 Canvas API. Your images are never uploaded to any server, never stored, and never seen by anyone else. This makes it safe for proprietary or confidential images.
We provide HEX codes (e.g., #4f46e5), RGB values (e.g., rgb(79, 70, 229)), and HSL values for each extracted color. You can copy individual colors by clicking on them, or export the entire palette as CSS variables or a PNG image.
We calculate WCAG 2.1 contrast ratios between each color and white/black backgrounds. AA level requires a ratio of 4.5:1 for normal text, while AAA requires 7:1. This helps ensure your color choices are accessible to users with visual impairments.
We use a quantized color frequency analysis with perceptual distance clustering. The algorithm analyzes every pixel in your image, groups similar colors together, and picks the most dominant representatives while ensuring sufficient visual variety in the final palette.
