I just started to use paint.net and I need help with swapping color values. I am re doing textures and what I am coloring is mostly red, but each pixel is a slightly different shade so I can't use the recolor tool. All I want to do is switch the red value with the blue value and keep everything else the same. I am a noob, so you might have to explain in detail what I have to do. This process would be much easier than taking each pixel and manually swapping the red and blue values. Thanks
