I'm not 100% sure but this may be Konica Impressa 50 which seems about to be discontinued and is rather slow. However if you can get it the newish Agfacolor Ultra 100 claims to have really vibrant colours. Alternatively Kodak Royal Supra (may be called something different in US) seems to be well thought of but that is about to be replaced by something called Elite Colour! Never used any of them I quite like bog standard Kodak Gold, Agfacolor Vista & Konica Superia Super!
