Paint colors to match Weber?

It's fairly common for people to find older Webers and rehabilitate them. In many cases there are chipped places on the lid or body, and touching these up with high-temp paint to prevent rust is pretty straightforward, if it's black. Has anyone found good matches between the blue, red, and/or green Weber colors and available brands of high temperature paint? If so, that information could help someone avoid having to buy several different brands to try to find the best match.
