Tile customising

[partian]

This is just my OCD kicking in however, I am wondering if their is a way of re-colouring a program tile of a program?

Sure there is. Depends on what you need.
You could use oblytile and / or create your own or change personalization to high contrast.
Can do, with Paint Shop, Xara, Oblytile, etc...
