Colorblindness & Game Readability

Color is how players find the objective, track threats and enemies, and act on time. Simulate every major color vision deficiency and tune hue, contrast, and saturation so critical information stays readable for all players. Live-service titles demand instant recognition of ability states, cooldowns, and threat indicators, enemy silhouettes and navigational assistence.
