HSL 转 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 之间的转换在数学上是精确且无损的。两种颜色模型都可以表示完全相同的 16,777,216 种颜色范围（对于每通道 8 位颜色）。在它们之间转换可以保留准确的颜色值，而不会产生任何质量下降或近似值。

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。由于显示技术、校准和制造工艺的差异，不同设备对 RGB 值的解读也存在差异。这种现象被称为色域变化。专业的工作流程会使用色彩校准工具来尽量减少这些差异，但不同设备之间难免会存在一些差异。
