I am probably going to take apart my Pearl and clean off the Sharpie although I can't see where my blue Sharpie is affecting the performance of this color changing program. I suspect this program simply activates the other LEDs rather than changing the color of the white LED, if the white LED can even be changed. So that is why my blue Sharpie is not making a difference here?
I could not get the pics to show how deep, solid and saturated the color of the trackball is after using this program. All the pics look like the trackball color is faded, but it is not.
Look at the chrome and inner rings that the trackball reflects. The one with the red trackball, that ring is about right in terms of color.
Anyway, there is a FREE trial, so install it and give it a try. Takes about two minutes to install.
