I have a png image that I’m using with GIMP that is only one color. I would like to change this color to a different color. Is there an easy way of doing this?
If you mean one solid color over a transparent background then it is easy:
- Set the alpha lock for the layer (checkerboard icon in the “Lock” line at the top of the layers list)
- Bucket-fill the layer (without any selection) with the required color, the alpha lock will ensure the opacity of pixels isn’t changed.
