Change mouse colour losing mouse in game

If anyone has found a way to change the mouse colour please help or can it be an option in the customize layout put in by NCsoft please losing the mouse cusor in game and slows down my attacks seems to blend in with the background love the game through just want the option for different mouse cusor colours and can we get more slots for Nightfall can not want for it

Mouse Colour: No option. But! The pointer shows a green border when a character is highlighted.
Extra Slots: It's likely.

In future could you please post something easier to read? Full stops would be nice. ^^
