Rovertech 2.0

Hi, I have a tahiti tourer, and wish to respray it in polynesian, how do I change the colour in paint shop pro or similar, as I want to see what it looks like before I change it.
Thanks.

(sorry if this is wrong place to post this, cannot find suitable area!)

Guides on here mate, look on the toolbar to the left under colour change...
