Choosing a color string representation

[Capi Etheriel]

I'm trying to implement a mixin that generates IE-specific filters to use as a fallback for RGBA. Yet I'm finding it really hard to consistently turn rgba(0,0,0,0.7) into #00000070

Mostly because green($color) returns 0 (not 00). and rgb(0,0,0) returns 'black'.

Am I missing something?

use the ie-hex-str($color) function that comes with sass and compass.

Sorry, it's not well documented. We use it in our filter-gradient mixin. It takes a color and returns a string like "#AARRGGBB" but with the quotes.

Hunt & pecked on my iPhone... Sorry if it's brief!

Why would Microsoft decide to put alpha before RGB…? I can only ever think of alpha being the fourth channel.

[Jacob Moen]

It depends.. ARGB or RGBA. Sounds like you're more familiar with the latter. But both are in use. :)
I don't know why the first is chosen, but it probably makes more sense in certain scenarios.

And I understand that… Microsoft Access, I think?… used #BBGGAA for color codes.
