Pantone 至HSL

HSL provides intuitive color manipulation by separating color properties: Hue controls the base color, Saturation adjusts intensity (from gray to vivid), and Lightness controls brightness (from black to white). This makes it easier to create consistent variations, adjust colors for accessibility, generate theme variations, and maintain color harmony compared to RGB or HEX, which mix color components numerically rather than conceptually.

在不同色彩空間的限制下，轉換在數學上是精確的。然而，Pantone 顏色以物理顏料的形式存在，而 HSL 描述的是發射光，這造成了內在的差異。大多數標準 Pantone 顏色轉換非常準確，但某些特殊顏色（例如金屬色、螢光色）超出了數字色域，只能進行近似計算。對於關鍵應用，請將數位結果與標準照明條件下的實體色板進行比較。

Use HSL when you need to: create color variations while maintaining consistent hue, adjust saturation for different UI states, generate light/dark themes from base colors, ensure accessible color combinations by adjusting lightness, or implement dynamic color systems that respond to user preferences. HEX is better for static color definitions, while RGB is preferable for color mixing in graphics software.

HSL simplifies creating color harmony by working with hue angles: Analogous schemes use hues within 30° of each other, Complementary schemes use hues 180° apart, Triadic schemes use three hues equally spaced (120° apart), and Tetradic schemes use two pairs of complementary colors. By maintaining consistent saturation and lightness values across these hue variations, you can create cohesive palettes that work well together.

由於瀏覽器和設計工具實現 HSL 到 RGB 轉換演算法的方式不同，尤其是在特殊情況下，顏色會有所不同。此外，顯示器校準、裝置功能和色彩設定檔也會影響顏色的顯示效果。對於關鍵應用程序，請在目標平台上測試 HSL 值，並考慮使用顏色管理系統來確保一致性。
