Im wanting to edit a certain color in a wallpaper but cant seem to figure it out or find any useful information. Im wanting to edit everything in Red to #1abc9c. Is this possible and any useful info is greatly appreciated...Thanks in Advance.
Im using GIMP 2.10
First, add an alpha channel.
Second, color to alpha and choose black.
Third, lock pixels transparency.
Fourth, select the red areas and fill with #1abc9c.
Fifth, create a new background layer at the bottom of the stack and fill with black.
After the color-to-alpha, you have semi-transparent pixels. If you lock the pixels, make a selection and fill with a color, you leave out the semi-transparent pixels, which is why you have to add the black background to fill the holes. Instead, after the color-to-alpha, you can bucket fill the whole layer (no selection) in Behind mode. This will fil the transparency with the color.
