HSL 轉 RGB

HSL organizes colors by human-understandable attributes (hue, saturation, lightness) making it intuitive for design. RGB structures colors by the amounts of red, green, and blue light needed to create them, which aligns with how digital displays work. They represent the same color space but organize it differently.

Use HSL when you need to: create color variations while maintaining the same hue, adjust saturation for accessibility, generate tints and shades, or create harmonious color schemes. HSL's structure makes these operations much more intuitive than working directly with RGB values.

是的，HSL 和 RGB 之間的轉換在數學上是精確且無損的。兩種顏色模型都可以表示完全相同的 16,777,216 種顏色範圍（對於每通道 8 位元顏色）。在它們之間轉換可以保留準確的顏色值，而不會產生任何品質下降或近似值。

RGB values use 8-bit integers (0-255) because this range provides 256 possible values per color channel, which offers sufficient precision for human perception while remaining computationally efficient. 256 values correspond to 2^8, making it convenient for binary computing systems.

不是。由於顯示技術、校準和製造流程的差異，不同設備對 RGB 值的解讀也存在差異。這種現象稱為色域變化。專業的工作流程會使用色彩校準工具來盡量減少這些差異，但不同設備之間難免會有些差異。
