oklchとかoklabがこのために存在している

哦原來oklch跟oklab來自同個人。不過是的，okhsv跟okhsl只是表現方式跟我們傳統用的選色器樣子一樣而已。

其實我記錯了，應該是oklab才對。以前是看到他講解才知道的。然後就有各種類似的分支 youtu.be/fv-wlo8yVhk?si=HrIP…

OKLAB color interpolation grids using the #MindfulPalettes no. 277 color palette

Announcing the release of v0.9.4.1 - it's a Hotfix release. Only one new item in here - a new Color Match mode using the OKLab color space. It's a little different from CIELAB but likely you won't notice a ton of difference. But try it out and see what you think. You can also now go into Settings and choose between Standard Luminance and OKLab L* for your Standard mode luminance calculation. This I think is strictly an upgrade, though it will change your old projects a bit. Otherwise it's fixing issues found with the new Rendering infrastructure and some other behaviors.

a few days ago naoyuki uchida put out the oklch paper, a clean three parameter extension of oklab, and it raised a fair point that my helmlab metricspace looks like it overfits. instead of just replying i said i would come back with a proper data backed answer, so i ran the test myself on every applicable dataset with one stress definition for everyone. here is the whole thing as a short q and a thread 01 q: does helmlab metricspace overfit a: yes but its source dependent, not global. the oklch paper by naoyuki uchida raised this about Helmlab Metricspace so i sat down and stress tested it properly. i put metricspace up against oklch , ciede2000, cielab, oklab and cam16 ucs on 8 color difference and discrimination datasets, all scored with the exact same garcia stress so its apples to apples. quick map of the result below, the rest of the thread breaks it down

built this gradient tool several months ago without codex/claude. made some beautiful presets using OKLCH / multi-point OKLab, you can see how they differ from linear RGB and export them easily. one more thing is the mix curve. it lets you control the overall shape of the gradient, which is the most fun I think. use it: wrap-gradient.vercel.app #buildInPublic
