Recolor (recolor.page) is a free website color changer: load any page by its address or as an HTML file, press Space, and the
whole page repaints in a new color palette, live. No account, and uploaded files are never stored.
Load a page. Type a web address, upload or drop an .html file, or pick a sample page.
Press Space or Generate. Each press is a new palette and the page repaints in it; lock the colors you keep and drag them into order.
Export. Copy the palette as CSS variables, a Tailwind v4 @theme block, SCSS, JSON, a hex list or a Coolors link.
