模块文档描述传入的颜色。
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：
