Colors

Colors are used to distinguish different players in StarCraft and StarCraft II.

StarCraft

In multiplayer matches, players cannot choose their own color before a game starts.

Player Number	Color	Terran Name	Zerg Name	Protoss Name
1	Red	Elite Guard	Tiamat Brood	Ara Tribe
2	Blue	Mar Sara	Surtur Brood	Sargas Tribe
3	Teal (most common hero color)	Kel-Morian Combine	Fenris Brood	Akilae Tribe
4	Purple	Antiga	Jormungand Brood	Furinax Tribe
5	Orange	Delta Squadron	Garm Brood	Auriga Tribe
6	Brown (Green on desert maps)	Omega Squadron (StarCraft), Atlas Wing (Brood War)	Grendel Brood	Venatir Tribe
7	White (Green on ice maps)	Alpha Squadron (StarCraft), Cronus Wing (Brood War)	Baelrog Brood	Shelak Tribe
8	Yellow	Epsilon Squadron	Leviathan Brood	Velari Tribe

StarCraft II

Players are able to choose their color before a custom match starts.

There are eight player colors available in games of less than 7 players: red, blue, teal, purple, yellow, orange, green and white. More colors are available in games with 8 players. Note how units are specifically colored on certain tilesets so that they don't blend into the background.

In single-player missions, colors are not explicitly associated with force names, but red terrans are usually The Dominion and blue Raynor's Raiders. The Tal'darim protoss faction are teal/aqua. Kerrigan's Swarm is consistently colored purple in Wings of Liberty.
