Benefit of this approach, it is a small generator rather than using a fixed lookup. Hence, the examples are only some samples possible. You can use an array with three values or a hex as a string for colors. Works in the IDE with an preview.
Lovely effect. Do you think it could easily be bound live to a rectangle's color? Then that could be animated live by hype? (The rectangle could have 0% opacity and just act as a lightweight "rig").
Alternatively maybe the tones are by default registered in additional HTML attributes?
Amazing, I love it!!! I imagine there are some color combinations that don't animate well, but I think the example is a pretty nifty effect. Nice work .
I'd love to see folks show off if they use this extension.
