Here are the outgoing colors and what they are being replaced by. I'm not sure if the color we saw on TV was the new Red Rock or if it was Crystal Red Tintcoat. I'm pretty sure the stock pics from GM are of the new Red Rock color which sucks compared to IOM.
(GCN) Victory Red exterior color replaced by (G7C) Red Hot exterior color
(GCO) Rally Yellow exterior color replaced by (G7D) Bright Yellow exterior color
(GCR) Inferno Orange Metallic exterior color replaced by (G7P) Red Rock Metallic exterior color
