Frequently Asked Questions
How does this color palette extractor work compared to Coolors and Canva?
Unlike cloud-based tools that upload your images to remote servers, Atlyxen Tools runs 100% client-side inside your browser using HTML5 Canvas quantization and color histogram clustering. Your proprietary 3D renders and photos remain completely private while generating identical or superior precision.
What color formats can I copy?
You can copy standard 6-character hexadecimal codes (#38bdf8), RGB strings (rgb(56, 189, 248)), HSL coordinates (hsl(199, 94%, 60%)), and CMYK print formulations for commercial prepress.
Can I export the palette directly into web code?
Yes! The tool automatically formats your swatches into standard CSS Custom Properties (:root variables), Tailwind CSS theme color objects, SCSS variables, and raw JSON arrays.
What image formats and file sizes are supported?
You can upload PNG, JPG, WebP, SVG, and AVIF files. Because all processing executes locally in your browser RAM, there are zero arbitrary file size limits.
How do I pick a specific color that was not in the automatic palette?
Click the "Live Eyedropper" button in the top action bar, then click anywhere on your image preview. The exact pixel color will be sampled and added directly to your palette.
