I'm sure Google's Material 3 """designers""" will make use of the built-in colour mixing if it reduces payload size.
A) color-mix(in srgb, var(--primary-color), white 50%)
B) #abcdef
For me to give up scss, there needs to be a minifier that calculates colors ahead of time and emits them plain, the way scss does. (Maybe there already is, who knows)I beat myself up about performance issues like that all the time and have to catch myself to go do something more useful instead.
