Load one current game screenshot, choose a stress lens, then compare two signals that players must tell apart. Start with ally versus enemy, health states, rarity, interactables, or minimap markers.

Waiting for screenshot Waiting for screenshot MeasurementContrast uses the WCAG relative luminance formula for the two sampled sRGB colors. It only describes this pair and is most meaningful when the colors are expected to touch.
HeuristicSeparation retained compares linear RGB distance before and after the lens. It is a directional warning, not a perceptual threshold or pass condition.
Mission review prompts
- Can players identify ally, enemy, warning, success, and failure without hue alone?
- Does text remain readable over the brightest, darkest, and busiest gameplay backgrounds?
- Do minimap markers differ by shape, label, position, or pattern as well as color?
- Are selected, disabled, unavailable, cooldown, health, and damage states still unambiguous?
- Can an icon, label, pattern, animation, position, or sound reinforce every critical color signal?
