Swapping two colours in an image

[rich2005]

There will be a few ways. One way

1. Color -> Color-to-alpha to remove the white logo
2. Enable Alpha lock (icon top of layer dock)
3. Fill the image with white
4. Un-tick that alpha lock icon
5. Set the required color. Use the paint tool in 'behind' mode' and carefully paint in the lettering.
