Generic Lorcet 10/650 made by Malinkrodt are not white. They are blue with an imprint of M361. Perhaps you received generic "Lortabs" and confused them with the Lorcet 10/650 that is being referred to.

BTW, I have taken brand, Watson and Mallie Lorcet 10/650 and didn't really notice a difference. I was on Mallie Lorcet for a while and kinda got used to them. This was before I learned about Norco's and decided to switch to 10/325's to lower my APAP intake.
