Several pseudo functions accept different numbers of parameters, the rightmost parameters are then optional, original ones don’t change their meaning. In CSS3: Color rgba() and hsla() have been added without taking advantage of this polymorphous capability. They also have been criticized for always denoting the alpha value as a number in the range 0.0–1.0, not as a percentage.

Could we therefore make 

  rgb(100%, 80%, 60%, 40%)
  hsl(300deg, 60%, 40%, 20%)
  rgb(255, 0, 64, 127)

valid in Level 4?
