Ah that's perfect! Looks like it's doing exactly what I wanted. Just one other thing, when I apply the recolour is there any way to have it so I can put in a specific RGB colour. At the moment it just comes up with 2 sliders. Thanks so much!!

Thanks so much for taking the time to reply! I probably should've said, I'm using Affinity Designer and I have attached the image. Trying to change everything green to a blue. Will these methods work with designer do you think?

Hi, so I have a PNG file. It is fairly basic, and has a large part of its background and some other text etc. as a single solid colour (A) that I would like to change to a different colour (B). So basically, how do I change everything that is Colour A to Colour B, preferably the easiest and quickest option if there is one! Thanks so much in advance!
