Bruce, I repainted my gauge needles quite easily a few years ago. There really isn't much to them however, it is essential that you mark where you needles point with key on and off and in access. mode to get them accurate again. JohnWPB did a good write-up after I did mine that is quite thorough.
An easy way to change the color of your gauge needles Have a look, it is about a 1-2 on a scale of 1-5
