Yes, good points, I see where you're coming from. The reason I suggest hexa is because it seems to be a CSS convention that the name of a colour function implies what arguments the function should take, or at least the colour model of the input; e.g.,
rgb(255,0,0) rgba(255,0,0,.5) rgb(100%,0%,0%) rgba(100%, 50%, 0%, 0.5) hsl(120, 100%, 50%) hsla(240, 100%, 50%, 0.5) Because of this, I would guess that most designers would intuitively assume a function called rgba() would accept only rgb and an alpha channel, just like the 'real' rgba. But then again, I'm not sure what the convention is for Sass on function names. I would be inclined to go with whatever is most intuitive from a CSS author's standpoint. Another point to consider: if rgba is used as the Sass function name, then there could be confusion between the following: rgba(100%, 50%, 0%, 0.5) rgba(100, 50%, 0%, 0.5) The first would output an rgba value but the second would output an hsla value. The only difference between these two is one percentage symbol. If we really do want a universal colour function that can take colour values in any style, the surely the function should be called color(), colora(), or cola()?
