I'm learning SASS and I tried to use background-color: darken(currentColor, 25%); to make the background color darker than the text, but when I tried to transpile it to CSS, I got an error message that currentColor is not a color.
I kind of understand why this happens, but I can't find a way to make it work, and I have a reason to keep using currentColor. Is there a way to make SASS perform color functions on currentColor?
