Just started experimenting colorizing with GIMP. When I add a layer on the pop up window I choose foreground color (which has been set previously) however I keep getting a grey shade no matter what color has been chosen before. Any ideas how to fix this ?
I got the same when I had chosen my new image to have greyscale colors, not RGB. That must be selected in the advanced options in File > New.
The user interface happily allowed me to choose any FG color, but new layer was greyscale, if it were not selected to be transparent.
So, open a new image and select the Colour space = RGB.
