Description

Pattern for matching actually valid RGB values.

  • validate separator (mixing spaces and commas between values is not valid)
  • validate if comma is used as separator if alpha channel is set
  • validate units (mixing percentage with integers is not valid)
  • extract r, g, b, a, separator and unit with named groups
