Ok im making a wallpaper and I change the channels just messing around and it turned this cool yellow and now I want to keep it that way so how do I do that??

a pic so you know what im doing

Really, I see that your wallpaper is good and the truth like that this well but he lacks something, but not that it is, you needed more opinions from others =)

So you turned off the blue channel...hmm the only way I know how is to flatten the image. But i'm not sure you want to do that, since you won't really be able to mess with it anymore...

you could always just try getting rid of all the color, and then filling in those spaces with that yellow...or playing with blending options, especially hue/saturation/color.

Yeah I thought about that but the black parts also got kinda messed up or changed and when I flatten the layer it turnes the normal color not the yellow what I did to get it that color was only leave blue and green
