support for currentcolor

[lionelB]

It would be nice to support color(currentcolor color-adjuster())

by the way, thx for this project !

It's impossible since this will require computation on runtime.
currentcolor depends on the cascade.
I will add a note in the README.

[lionelB]

thx.
I guess this apply also to the #3

Could it not walk up the CSSOM to find a color definition? If none is found, default to black. I understand that this is not specification-compliant, but neither is this library's implementation of var().

[MoOx]

It just can't. We don't have the DOM and only the DOM say the truth.

[stevenvachon]

We don't necessarily need the truth when we're compiling.

[MoOx]

For the exact same reason postcss-custom-properties is limited to root, I will never this kind of stuff.

[stevenvachon]

Alright, fair enough.
