Show HN: A free tool to extract color palettes from any website

Hey everyone!

I’m Nestoras, the creator of colorize.design a tool that extracts color palettes from any website. Just enter a URL, and it generates color palettes based on the site's design. Several palettes are created by analyzing both the visual layout (dominant colors from the favicon and homepage screenshot) and the website's HTML, CSS, and JS files.

This project was born out of my own frustration. Whenever I came across a beautifully designed website, I wanted an easy way to grab its color palette without manually inspecting elements or using browser extensions.

How it works: Uses Puppeteer to load the website, take a screenshot, and extract dominant colors. Groups colors using a nearest color algorithm to reduce redundancy and improve the palette. Extracts colors directly from the website’s CSS, HTML, and JS files. Allows users to edit extracted colors and download the full palette. Offers an API for developers who want to integrate this into their workflow.

I’d love to hear your thoughts! Any feedback on the user experience, design, or overall presentation would be super helpful. What features would make this more useful for you? Let me know what you think.

    Awesome tool, well done! I had to send the product website color palette to the documentation team and you just saved me from having to search for tailwind colors in the source files.
