Stu MaschwitzMade a nifty little After Effects preset that interpolates color keyframes in LAB rather than RGB, for smoother transitions.
Might become part of Prolost EDC, in the meantime Prolost Beta subscribers get to play with it. https://proloststore.com/products/beta

@5tu There is a way to traverse opponent signals, that can side step the number fornication of Lab.
@troy_s As usual, I am seeking creative options rather than some ultimate “correct” method. But I’d love to see whatever research in this area has captured your interest.
@5tu It’s not really research. It’s a formulation that is closer to RGB, using Judd’s approach. There is no “correct” because the human visual cognition system doesn’t work on discrete magnitudes.
@5tu For example, place the gradient you generated on a different field, and your visual cognitive response will be **wildly** different. So different that you’d change the way you arranged the gradient.
That said, Lab doesn’t follow the basics of opponency that RGB does.
