Support colorspaces with alpha?

[jpoz]

Wondering if you're planning on supporting colorspaces with alpha channels?

There is no conversion involved in the alpha channel: Alpha value is a single additional channel that doesn't change as color space changes. That's why there is no alpha anywhere in go-colorful: it's not necessary.

What specifically are you missing or would you want to see?

I'm trying to blend two colors with alpha values. Just wondering if you're going to add alpha compositing.

Oh, I see. I guess you mean using the equations presented on wiki, right?
It's not planned, but I would accept a non-invasive PR adding it.
