> manipulate your RGB images as much as you like; just do it in the OKLAB color space
Be careful, OKLAB also isn't quite handling energy correctly (Or, the gradient of the energy slope in this color space had quite some irregularities). In most cases you can get a more "natural" transition (like blue doesn't visually shift to purple when transitioning to white), so make sure you know what you are doing.
