YouTube Timeline Color Changer

Tired of YouTube’s default blue progress bar? YouTube Timeline Color Changer lets you personalize your viewing experience by changing the color of the played portion of YouTube’s video timeline—exactly how you like it. Choose from quick one-click presets or pick any custom color to match your mood, theme, or accessibility needs. This lightweight, privacy-friendly extension works seamlessly across all YouTube pages, including during navigation within YouTube’s single-page app. It instantly applies your chosen color and remembers your preference using Chrome Sync—so your timeline stays consistent across devices and sessions. You can even optionally tint the buffer (loaded) portion of the bar for a fully customized look. Built with minimal code and zero external dependencies, the extension injects only a tiny CSS override directly into YouTube pages—no tracking, no ads, no bloat. If YouTube updates its interface, the extension is designed to reapply styles automatically after page transitions. Perfect for creators, designers, streamers, or anyone who wants a more personalized or accessible YouTube interface, this tool puts visual control back in your hands—without slowing down your browser. Install YouTube Timeline Color Changer today and make YouTube truly yours—one pixel of progress at a time.
