Gus Mueller posted a tweet asking which is the best way to draw a gradient recently, which triggered me to formalize an idea I’ve had for some time.
It has bothered me that some color gradients are not perceptually uniform. Some have a dark spot in the middle and some are easily divided into separate regions. It should be possible to re-distribute the colors such that the change is perceptually uniform.
I wrote the following experiment to test if it would be something usable.
