I have attached an image to hopefully explain better, but if say I have an image that ranges from color 'A' to 'C', and I want it to range from 'B' to 'D' instead - what is the best method?
I'm sure it has something to do with color range or similar. I'm aware of the Hue + Colorise method, but it doesn't allow me to pick the end point colors (B and D).
(Also ignore the shadow in the image.)
