Getting started
First off, grab yourself the hottest new release at https://github.com/ad2017gd/RainbowTaskbar/releases.
RainbowTaskbar is a portable app, so there's no installing required.
This is a one-time prompt, only visible if there is no config file present. You can always toggle it under the system tray menu. If you change the location of the executable, make sure to toggle the option in the menu, and set it back on.
This will pop up when you start RainbowTaskbar if there is an update available. If you click Cancel, but change your mind, you have to manually remove the registry key located at HKEY_CURRENT_USER\SOFTWARE\RainbowTaskbarNoUpdate
.

Bitmaps
Bitmap (.bmp) images can be added on RainbowTaskbar. They can also blend with other color effects by altering the transparency. If your bitmap doesn't work, try opening it in Paint and saving it again.
