If you want to venture into doing it yourself, the "TV Yellow" rattlecans from ReRanch.com are as dead-on perfect to the original color as their Gold Top paint is. One word of caution, the original "TV Yellow" on vintage Gibson LP Specials/Jrs. was a bit brighter yellow to start out with when new. If you've seen pics of vintage Gibsons, the brightness of the yellow fades/creams out a bit with age/UV exposure. The Gibson re-issues of these guitars that were selling a while back had paint that looked more like a vintaged one, than the original color.
I bought a can of the ReRanch.com TV Yellow as there is another "Fenson" on my build less, once I get rid of my current project backlog; not sure if I'd call it a Tele Jr. or an LP Esquire, single bridge P90....
