範例
- Uploading a chart that uses red and green bars, then selecting Deuteranopia, shows both bars at nearly identical brightness — a strong signal to add patterns or labels。
- A UI screenshot run through Tritanopia simulation reveals that blue buttons and grey disabled states become visually indistinct。
