10 years later, after the '98 introduction of StarQuest inserts, Upper Deck printed a 2008 set which would also feature color over printing effects found more commonly across the hobby. Overshadowed by so many other inserts and sets from 2008, it can be a fun challenge to put togehter a player "rainbow" due to the amount of cards printed in that era. While more popular Topps' Moment's and Milestones or UpperDeck's Documentary / A Piece of History draw more collectors, this set has been a real joy to attempt to collect. Card color breakdowns include: 

Common which were inserted 1:8 packs and feature a Silver background.

Un-Common cards feature a Copper background color.

Rare cards include a Cyan color front and back.

Super Rare StarQuest cards have a true Blue background.

Ultra Rare cards have a Gold background and "Ultra Rare" printed on the rear oval.

Majestic cards were inserted 1:16 packs and have a stunning, Black background.

The final parallell is a First Edition which featured a flat, foil Green finish, and were 

inserted only into packs of 2008 Upper Deck First Edition.
