What RainbowTaskbar is
RainbowTaskbar is a free Windows app for customizing the taskbar with colors, animations, images, websites, and other effects. It supports web configurations as well as instruction-based configurations. Web configurations can respond to mouse interaction, use WebGL, canvas graphics, and video, and use the RainbowTaskbar API to adjust taskbar style and transparency. The app also supports taskbar positioning, transparency controls, and multi-monitor setups that may involve scaling and positioning. Its Workshop lets users download configurations without an account; uploading one requires signing in with Google or GitHub. RainbowTaskbar is portable, but it needs the .NET 8 runtime if that is not already installed. The maker warns that it conflicts with TranslucentTB, which should be closed before running RainbowTaskbar. First released in 2021, it is described by its maker as a passion project. The free and open-source app is available for Windows.
