bjornornorn, thank you! I’m looking forward to trying it out!
I’ve been using a variant of JzAzBz for the last year or so. Perceptual color spaces make image generation much easier. Can you help me understand how JzAzBz falls down?
- bjornornorn 6y agoThe largest difference is that JzAzBz has been designed to model lightness perception of very bright colors and very dark colors. Depending on your use case this could either be useful or a problem, since it means that you have to be careful with the scaling of the input data to JzAzBz. E.g, if you scale a color by some value before converting to JzAzBz, the predicted hue will be different than without scaling. Oklab will predict the same hue regardless of scale (but could also mean it does worse for extreme colors). So it is a trade off, with oklab being designed to be less complex.
- quag 6y agoThanks! That helps, and JzAzBz is complex when it comes to calculations.
