Thanks for the advice on how to do it Micky
I did it all with a brush tool and my pen tablet in Gimp. One section at a time. My Mrs saw what I was doing and wanted a go, thats where the 2 big stray dots come from.
I know the new ST is not to everyone's cup of tea, but I just wanted to have a go at changing colour to see what I could do, and thought I would use this as we have only seen the red so far.
I still personally like it, but im not gonna buy one. I want something bigger and more powerful.
I think my favourite of above is the dark grey
