Blue: WoW Cursor help

I'm having great difficulty seeing the hand/pointing finger icon during graphically busy fights. Is there any way I can change the color or the brightness of the pointer icon so it contrasts much more versus the surrounding graphics on screen?

I have my graphics set so it's pretty vivid and colorful as it is to compensate for my crappy eye sight, and I don't have a problem with this when I'm out soloing around or in 5 mans when there aren't a lot of people standing around or AOE going on, it's just when the screen is real busy. During those times I can't find where my pointer is at and end up losing people because I can't click on the raid box to heal them.

If there is some way to make the thing stand out better I can find it faster and all will be well. HALP! please.
