I was trying to recolor an image using the appropriate tool. I followed the instructions on getpaint.net, but when I used the tool, it gave me the inverted version of the color I wanted. I uninstalled and reinstalled twice. I searched for similar issues and found none. I even went so far as to paint the color I wanted, invert the photo colors, use the picker tool, and set the inverted color as my secondary. It turned out the actual color I wanted. What's going on?
