模块文档  

这个文档嵌入自Module:Sandbox/DGCK81LNN/颜色描述/doc。

描述传入的颜色。

颜色描述参考资料：http://www.procato.com/rgb+index/

2020年3月31日 (二) 10:05 (CST) 更新：现在颜色描述更详细了！

支持的颜色格式：

• HEX色号（#ace，#abcdef，不区分大小写）
• RGB色号（rgb(123,45,67)，rgb( 123 , 45 , 67 )，括号内空格随意，“rgb”必须小写）
• HSL色号（hsl(123,45%,67%)，hsl( 123% , 45% , 67% )，括号内空格随意，“hsl”必须小写）
• RGBA、HSLA色号（rgba(123,45,67,89%)，hsla( 123% , 45% , 67% , 89% )，Alpha值会被忽略）
• CSS颜色名（aliceblue，必须小写）

User:DGCK81LNN/color block使用了此模块。栗子：

{{User:DGCK81LNN/color block|#ace}}

亮蔚蓝

{{User:DGCK81LNN/color block|#abcdef|rgb(123,45,67)}}

¤亮蔚蓝、暗猩红

{{User:DGCK81LNN/color block|hsl(123,45%,67%)|aliceblue}}

¤亮绿、蓝白

由于一些奇怪的特性，colour模板输出的颜色值不能直接传进来。

{{User:DGCK81LNN/color block|{{ColorOps|+50|#339988}}}}

这样会输出：
