± On the other hand, we could go the calc route and require a space, so that ± "adjust-alpha(red, 50%)" would set the alpha to 50%, but "adjust-alpha(red, ± + 50%)" would make the alpha 50% larger. Seems kinda clumsy, though. Argh, sent that mail too fast. Another option is to use multiplications. color(red, alpha * 75%) vs color(red, alpha 50%)Received on Thursday, 9 May 2013 20:18:57 UTC
