+1 for white(). 


1. Cocoa's equivalent is colorWithWhite:alpha:

https://developer.apple.com/library/mac/documentation/Cocoa/Reference/ApplicationKit/Classes/NSColor_Class/Reference/Reference.html#//apple_ref/occ/clm/NSColor/colorWithWhite:alpha:

I've checked popular answers on stackoverflow that include references to variants of this function: developers seem to be using it properly, and I haven't seen anybody confused about it.


2. CSS is tied more closely to RGB than CMYK

If there was black(x) I'd expect it to be a shorthand for cmyk(0,0,0,x), but use of actual CMYK colors in CSS can be a can of worms (it should be subject to color profiles, but then black(0) may be different than rgb(0,0,0)).

However in the RGB world white(x) can be simply explained as rgb(255*x, 255*x, 255*x), but the same doesn't make sense for black: rgb(0*x, 0*x, 0*x).
