I’m still looking at ways of perfecting the comic-book production workflow. One of the remaining problems is how to enforce consistent colours from frame-to-frame and page-to-page. Easy with Poser renders. But one of the problems in generating AI images from Poser renders may be that colours do not remain consistent across many images.
I just had an initial look around, and Sighmoan1’s simple Colourchanger Python script seems to be a simple local approach to what’s needed. He uses Python’s built in PIL image-processing suite of tools, and supplies a straightforward script.
This script can batch processes an image-set, replacing a specified colour with a new colour. With the useful option to add some wiggle-room via an additional setting for… “Threshold distance for colour similarity (default: 50)”.
Not so useful if you have a range of similar colours (e.g. browns) in images destined for a comic-book. But possibly useful for forcing consistency on one unique colour? e.g. if your sci-fi character’s alien cat should always be a certain shade of purple. A more common example might be enforcing a standard blue sky colour in a scene that stretches across many comic panels.
