"There are four socket types: red, yellow, blue, and meta. Any gem can be placed into any socket, and you will receive the bonus for that gem; however, if all the gems' colors match all the sockets' colors on an item, you will receive an additional socket bonus. The only exception is the powerful meta gem; which can only be placed into a meta socket, and a meta socket can only accept meta gems. In addition, if the meta gem's requirements are not met, that meta gem will not be activated, and you will receive neither the meta gem's bonuses nor any socket bonus from the item containing the meta gem. You can socket the meta gem without meeting the requirements, but the meta gem will remain inactive until you do meet its requirements (which can be done either by socketing new gems, or equipping new items containing the required gems). A meta gem requires you to have currently equipped items socketed with a certain number and color of other gems. These colors can be as either primary or secondary colors (see below.) (Note: Meta sockets are only found on high-end head gear.)"@el . "There are three colored socket types: red, yellow, and blue.
