Krylon Fusion (for plastic) "Satin Almond" is as close to perfect as I think you will find the the stock A4000 color. Let it cure for the full week though, in a dust free area.
I have a finished A4000 bezel that I can send you a photo of if you like so you can see it. It looks like brand new now, and it was one of the worst cases of yellowing I have seen before I did it.
