What qualifies as a red, yellow, and blue gem?
A gem that is red, orange, or purple counts as a red gem. A gem that is yellow, orange or green counts as a yellow gem. A gem that is blue, green or purple counts as a blue gem. Therefore, for the purposes of checking meta gem requirements, a purple gem counts as 1 red, 1 blue. This will be very important to meet the high requirement on Brutal Earthstorm Diamond.
