You have to have HTC Home Customizer installed on your phone. If you have the program installed, you find the folder where it is located. Usually it is under the program files/HTC Home Customizer/. Depending on where you installed it, it might on your storage card. Once you have found the folder unzip the file to program files/HTC Home Customizer/files/icons.

Then you should be able to find on your HTC Home Cutomizer program under icons, Red_Black.
