WhiteBuster, developed by kofifus, is a free Chrome add-on that aims to enhance the user experience by transforming white backgrounds on web pages into more eye-friendly colors. With WhiteBuster, all background-color values of rgb/a(255,255,255) and rgb/a(254,254,254) are converted to a selected color while preserving opacity.

One of the standout features of WhiteBuster is its ability to handle transparent items, iframes, and runtime-created elements. This ensures that even complex web pages with dynamic content can be transformed effectively. However, it's important to note that white background images cannot be altered by WhiteBuster.

While WhiteBuster strives to provide a seamless experience, it may encounter issues with poorly coded pages that rely on the background-color being white. However, the developer reports that no such issues have been identified thus far.
