Specification
https://drafts.csswg.org/css-color-5/#relative-alpha


Summary
Relative alpha colors refer to an origin color, and only change the alpha 
channel. The meaning of alpha channels is defined in CSS Color 4 § 4.2 
Representing Transparency in Colors: the <alpha-value> syntax.

Motivation
Relative alpha colors provide a direct CSS way to derive a translucent version 
of an existing color without rewriting its color channels. Authors currently 
need to duplicate component values or create separate precomputed tokens when 
they want “the same color, different opacity.” The CSS Color 5 alpha() function 
preserves the original color components and only changes alpha, which reduces 
authoring overhead and makes color tokens easier to reuse and maintain.
