I want to recreate the following image at a much higher resolution, so it will be suitable for printing in large.
I have found a place where I can purchase a high-resolution version of the ice cream cone, as well as (a good imitation of) the font. The only difficult (to me) part of putting the image together is recolouring the stock photo to match the ice cream in the smaller image as closely as possible. I somehow want to keep the small-scale detail of the higher resolution image while preserving the colour of the smaller image. I was hoping someone here could explain to me how to do this.
The only software I have on hand is Gimp, so I would prefer to do it there. If doing this is for some reason next to impossible in Gimp and very easy in (some recent-ish version of) Photoshop, I might be able to get access to a computer with Photoshop for a few hours, but that would be much less practical for me.
(ETA: To be clear, I have permission from the creator of the image to do this.)
