Interior Paint.
When I did my driver side grab handle, the one I bought was from a truck with a darker interior then my truck. I just bought some paint that matched my interior from the dealership. It was a perfect match of course, and it came in a small rattle can so it sprayed on very easily. it was a little pricey (I think it was about $5), but it was the perfect match, so it was worth it to me.
www.genosgarage.com also sells color matched paint. Another way to get it perfect is to take a piece off the dash like the fuse cover and take it to a automotive paint store. They can mix up some paint that will match exactly and out it in spray cans.
