    Not quite sure what you're looking for here. If you apply that channel/mask to that picture, you get 'no black' - i.stack.imgur.com/IOyLP.png

I guess you have the wanted alpha channel as a separate image and the colored version should get it. In the next image both versions are separate layers in the same image:

enter image description here

If you insert a layer mask to the colored version you get normally a white mask like it has happened above.

  1. Select the content of the wanted mask layer and copy it to the clipboard

  2. Click the layer mask icon of the colored version by holding Alt key at the same time. That brings the mask under onscreen editing.

  3. Paste the new mask in place

Disable the wanted mask -layer. and see the result:

You can export as PNG if you want a single layer image which has the mask applied permanently (=as a new alpha channel). I wouldn't apply the mask in Photoshop (= Layer > Layer Mask > Apply) because I see it's a benefit to have the transparency in an editable mask.
