For color picking, I have just released two new color spaces based on Oklab, trying to improve on HSV and HSL. You can try them and compare with other options here: https://bottoss…

Just a small correction: Logarithmic != gamma encoded. Most software use sRGB encoding which is close to a power function (often referred to as a gamma function). Logarithmic encod…

Thanks a lot for the kind words!

Yeah, should be similar a lot of the time. Deep blues are the colors that are the most different.

Thanks! Regarding: “Cube is beautiful in the sense that it allows scaling the intensity without considerations, but it is quite awful in the near black psychovisual performance.” Y…

Yes, exactly. The results will be more accurate as in closer to perception of light (for rendering for example you would want a linear color space)

Nice! Definitely the the type of use case I had in mind.

There are a two different CIE LCh color spaces: they are cylindrical samplings of CIELAB and CIELUV, similar to how Oklab can also be sampled with cylindrical coordinates The compa…

The 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 us…

Not that familiar with XYB and its properties. Is there anywhere I can read more? Found some specifications, but not anything on its properties. I think this might be a case where …

Yeah, that’s pretty much why I didn’t include it. I haven’t really seen YCrCb used except anywhere for in compression, so didn’t think of including it (an neither do most papers re…

That is based on CIELUV, which is one of the spaces tested against in the article. CIELUV is useful because its chromaticity space is a projective transform of XYZ. That also means…

Yeah, both of those are good recommendations! I also think it is useful to focus on understanding the various experiments that have led to the different color models. The most impo…

Yeah, would be nice. I've been thinking a bit about following up with that. The generated dataset consists of a few thousand colors. The hue dataset is using 15 different hues only…

Author here. Wow, thanks a lot! If anyone has any questions feel free to post here and I can try to answer. I have another post that goes into more detail onhow software often gets…

I like to think of this somewhat differently. By using extreme values you are limiting your options. If you use #FFFFFF in a design you can't select a brighter color and you can't …
