I often find myself using and creating colour palettes for use in Observable pages. The documentation for various colour schemes and interpolators via D3 is pretty good, but I found less on what the implications are for various colour mixing choices.
So I thought I’d create a page that explores a range of colour mixing approaches suitable for Observable, that variously use D3, spectral.js, mixbox and chroma.js and show how they might be applied.
Comments or suggestions for improvements welcome.
