This addon was designed to compliment the enhanced colourblind mode features that were added to World of WarCraft in Patch 4.3.0.
To use this addon, simply open the Main Menu, click on Interface and then click on Help. A selection menu will appear beneath the checkbox labelled "Colourblind Mode" (see screenshot). Click on this menu and you will be able to choose a colour shader which best suits your type of colourblindness.
