Alright so I'm working on a wallpaper for a friend and while screwing around in gimp, I found the Channels dialog. Took out green and blue to give the entire image a blood red-ish look to it and it looked really cool. (Im a noob with gimp so thats why what follows.. follows)

Figured that if I saved it, it would ACTUALLY remove the colors, not just show it as "This is what it would look like if..." I was wrong. Spent the last hour googling around trying to find my answer, one link I found was an ubuntuforums post that described how to remove a single color layer (which worked fine) http://ubuntuforums.org/showthread.php?t=1404416

But I can only get it to work for JUST green or JUST blue, not both. Was hoping someone could walk me through how to do it.

"Layer > From visible" will always create a new layer with whatever your have in front of you. Disable color channels, run this command from menu, and you can save/export the file: since the top layer contains what you had when you disabled some channels, you'll see what you want.
