There is a new program to change the color of the Pearl trackball. It changes the trackball color to one of six that you want [blue, red, green, pink, aquamarine, yellow].
You can also set the time for how long the trackball stays on, 15 to 120 seconds.
Super bonus: The trackball is now super, super bright in the color of your choice. Much brighter than my Sharpie mod.
There is a free trial period at Handango. Download it now.
Note: This, and most other trackball color applications DO NOT work with OS 4.5.
