Frequently Asked Questions
CSS中何时使用HEX、RGB、HSL？▼
HEX（#FF5733）最紧凑且使用最广泛。RGB/RGBA在需要透明度（alpha通道）时最佳。HSL在颜色操作时最直观——改变色相旋转色轮，调整明度使其变亮/暗。在程序化生成颜色变体时使用HSL。
HEX 3位和6位表示有什么区别？▼
3位HEX（#F00）是每位重复的缩写：#F00 = #FF0000。仅当每对数字相同时有效。#ABC = #AABBCC，但#A1B2C3没有缩写。8位HEX（#FF000080）添加alpha透明度。
如何选择无障碍的颜色组合？▼
WCAG指南要求正常文本对比度至少4.5:1，大文本至少3:1。使用HSL快速调整亮度以改善对比度。深色文字配浅色背景（或反之），有足够的明度差即可确保可读性。
