About Colorful Treasure, from BoardGameGeek:

Travel around the world and look for glorious gems buried among the mysterious Wonders of the World! The colors of the Wonders hint at the types of gems that might be hidden inside. With careful deduction, a bit of memory, and a pinch of luck, you will collect the most valuable gems and become the legendary treasure hunter! Colorful Treasure is a memory game with a fun twist of deduction element in the tri-color card back. There are 10 different Wonders and each type of Wonder comes with 5 cards: 1 Diamond, 1 Treasure Chest or Key, and 3 gems of 3 different colors, whose colors are indicated on the card back. All cards are shuffled and placed facedown on the table. Players take turns to reveal 2 or 3 cards and collect one type of card(s). During the process, players get to deduce the potential card from the card back. Besides the competition on the set collection of 5 colors of gems, player can also steal valuable cards or diamond tokens from their opponents if they manage to get a set of Treasure Chest and Key!
