These tint-bases have changed twice since then. The formula 8 years ago wouldn’t exactly match in todays bases. The sheens have changed some too.
Unless you can find a store/someone with an old tint-base, you’re out of luck for an exact match!
We MAY have old RL formula’s, but again, it wouldn’t exactly match using todays bases anyway….
(I’m at an independant RL-paint retailer, NOT a HD!!)
If it’s for touch-up, it won’t match anyway, mainly because of wear/fade on your existing walls.
Sorry!
