Paste a palette and instantly see how well its colors separate under 8 vision channels — normal, red/green and blue/yellow deficiencies, achromatopsia and grayscale. Get a pairwise ΔE matrix, red-flagged confusion pairs, a lightness-ladder score and one-click fixes. All computed locally in your browser.
模擬採用 Machado 等人(2009)的線性 RGB 變換矩陣,作用於線性光(linear-light)空間,色弱按嚴重度在「單位矩陣 ↔ 完全型矩陣」之間線性插值;全色盲與灰度按 Rec.709 相對亮度直接去色。色差走 sRGB → CIE XYZ(D65) → CIE Lab,提供 CIE76 與 CIE2000 兩種度量,並可疊加 OKLCH 感知距離。判讀閾值:ΔE<5 幾乎不可分(嚴重混淆)、5–10 難以區分、10–20 可區分、>20 清晰。圖表配色建議任意兩色在全部通道下 ΔE≥10。
