Colors

As a tradition of RTS games, different colors are used to distinguish different players.

Red Alert
In Red Alert, the color of each country is hardcoded in campaign.

Campaign
GDI always uses Gold in the campaign. Nod forces always use Red in GDI missions; other than toxin soldiers who use Blue and Burgandy in Capture Jake McNeil and Seeds of Destruction respectively, the player faction in Nod missions always uses Red. Blue is used by renegade Nod factions, including Hassan and CABAL, and Hammerfest Base captured by Nod. The Forgotten uses Grey in Sheep's Clothing and either Light green or Green in most other cases.

Red Alert 2
In Red Alert 2 and Yuri's Revenge, noticeably more colors are used than in any earlier games.

Campaign
Each faction uses the colors from left to right in decreasing priority order when there are more than one houses of the same side in a mission. Violet is used by Vladimir's dreadnought in Hostile Shore. Purple is used by the primary renegade Soviet forces, namely Vladimir and Yuri in Desecration and Red Revolution respectively. Black is used by the Black Guard.

Skirmish
The 8 colors available for Skirmish are mostly the same as the ones from Tiberian Sun and Firestorm.
