+1 to rgba(color-value, alpha-value) or a new function that takes those arguments Eg: rgba(#f00, 0.5); rgba(#f00, 50%); rgba(red, .5); rgba(rgb(255, 0, 0), 50%); /* not particularly useful, but showing that any color value is acceptable */ rgba(#f000, 50%); /* here the 50% alpha would take precedence over the 0 alpha in the first arg */ As for darken/lighten/etc, I can't say I've used them much, but if others do, fair enough.
