Photoshop help: Colour my rims!!

Hi.
Anyone here able to change the colour of this wheel to a gunmetal grey with a white pinstripe?
Wanna see how it looks but don't wanna go and paint it all yet...

outline is a little bit chunky, but gives you a rough idea. (without selecting aaaaallll those spokes!)

Hmmm food for thought! I definitley prefer the white stripe. Maybe i'll keep the black or a darker grey???
Thanks heaps for doing that for me tinto!! Legend.
