Provide bulletproof RGB/RGBA regexp with css4 syntax support. You use capture groups matches to extract values.

RegExp	Color Space	Matches	Css Color Value
numberRGB	rgb	rgb(255, 255, 255)	<number>, <number>, <number>
numberRGB	rgb	rgb(.5, 25.5, 255.0)	"    "
numberRGBA	rgba	rgba(255, 25.5, 255, 1%)	<number>, <number>, <number>, <alpha-value>
numberRGBACss4	rgba	rgba(255, 25.5, 255, 1)	"    "
percentRGB	rgb	rgb(100%, 100.0%, .2%)	<percent>, <percent>, <percent>, <alpha-value>
percentRGB	rgb	rgb(100%, 100.0%, .2)	"    "
percentRGBA	rgba	rgba(100%, 100.0%, 10%, .2%)	"    "
percentRGBACss4	rgba	rgba(255 100.0 35 /.2%)	<number> <number> <number> /<alpha-value>
percentRGBACss4	rgba	rgba(100% 100.0% / .2)	<percent> <percent> <percent> /<alpha-value>
