| | 1 | To help differentiate units on a battlefield, most unit textures should make use of player colour: parts of the texture are marked as player-colour regions, and in the game they are colourised to match their player. |

| | 3 | This is controlled by the alpha channel of the texture - high alpha regions are unaltered, low alpha regions become strongly coloured, and anything in between gets a proportional amount of colouring. |
