Promo labels were often, though not always, a different color than the stock issue label. The record companies
wanted to distinguish them from "for sale" records. These albums were given away to DJs and the press, and there
were significantly fewer of them. Many collectors believe they are the best sounding because they were the first
ones off the presses and were made from fresh stampers.
Most promo labels are white, hence the term "White Label Promos" or WLPs. A few labels used other colors. Verve,
MGM and occasionally Capitol used yellow and Mercury used a variety of colors. Decca was the only label to use
pink - which they used until the late 60's, when they reverted to white. It's interesting and a bit surprising
that they chose pink, as they were a pretty staid company, and the pink promos stood out. Here's a question:
Can you call a non-white promo label a WLP? I do, but it feels kind of weird.
