I don’t have much experience with CLUTs but I have been thinking on whether it would be possible to generate one based on a limited palette and apply it in a natural way. E.g., I have the following arbitrary palette where the colors are in a particular order and some are more prominent than others:
Edit: sorry, I messed up the png as @samj pointed out.
Maybe include the cases where we disregard the prominence and / or order… I don’t know if this is practical but I see the utility of generating looks very quickly and easily based on palettes. Perhaps a tool already exists that I haven’t explored yet. Please direct me in the right direction. Thanks.
