Possibly one that does have colour in the name, Overlay mode looks promising https://i.imgur.com/0n90Baq.jpg (edit and ps - if using the image from the web site it is in indexed mode, change to RGB)
Thanks for the replies peoples.
I've tried both of those HSL and LCH which either produce peppermint greens or shadows. I guess Gimp can't do it so I'll have to try other options.
Thanks
