You have one chance to locate Red hidden amongst a mosiac of other colours. Dark Red is amongst them, but I'm only going to accept Bright Red. Sounds easy, but you'll only have a short amount of time to see the mosiac before it gets wiped, the mosiac is rectangular 16x8, it also won't be on display when it is prepared and the escape key has been disabled while the mosiac is shown. Once the mosiac is wiped, you can use your crosshairs to select where Red was on the board.
