Color in game UI: HUDs, inventories, and the logic behind status indicators

Game interfaces operate under constraints that no other design discipline shares: they must communicate critical information in real time without interrupting the player’s perceptual focus on the game world itself. The color systems that govern health bars, minimap legends, inventory rarity, and damage numbers are not decorative — they are information architecture. Understanding how successful games solve these color problems reveals principles applicable across any data-dense UI.
