StarCraft II

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

As of Patch 3.3.0, players are able to choose what colors appear for the player's, allied, neutral and enemy units for ladder and unranked matches.

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. Colors are changed depending on the tileset as to not impact

In single-player missions, colors are not explicitly associated with force names, but red terrans are usually The Dominion, blue are Raynor's Raiders, and pink Mira's Mercs. Moebius Corps and the Covert Ops Crew are both black terran, but the Covert Ops Crew uses a different skin set. The Tal'darim protoss faction are teal/aqua in the Wings of Liberty campaign, dark blue in Heart of the Swarm, and given their own red skins in Legacy of the Void. Kerrigan's Swarm is consistently colored purple in the single player campaigns, with feral zerg usually being colored orange and Amon Brood being colored red.

In the Legacy of the Void campaign, player controlled protoss Daelaam are colored blue, Purifiers are colored orange, and Nerazim are green. Both Tal'darim and corrupted Khalai are red, but the Tal'darim use a different skin.
