Data Viz Color Palette Generator (For Charts and Dashboards) (learnui.design)

This is great, thank you for sharing. I need something like this for my current project I'm working on... Much easier than trying to build a color palette manually.

I also recommend Color Brewer, which is integrated already in a lot of visualization tools, and has great options for display variants and accessibility options : https://en.wikipedia.org/wiki/ColorBrewer

Related, the OG, with research behind it- https://colorbrewer2.org/.

It's functionally very close to https://colorbrewer2.org, which has been online for more than 15 years. I think it's not a coincidence, and some credits wouldn't have hurt anyone...

Also, I have personally been using iWantHue to generate large palettes for more than 10 years now, and I'm still very happy about it: https://medialab.github.io/iwanthue/

See Fabio Crameri's colour maps for accessible yet pleasing schemes and gradients to accustom various vision impairments [0][1]. Ben Jann's collection also provides a valuable resource and inventory of recent and historic colour schemes included in different statistical packages [2].

Definitely not colorblind-friendly (color contrast too low)

Whenever I need colors for a chart, I type "12 bit" in my address bar and pray my browser hasn't forgotten the URL: https://iamkate.com/data/12-bit-rainbow/

I need output: * gnuplot pallete * css for web page

I like using https://coolors.co/ - press space to generate a new palette and lock in colours you like

Strange that the SVG output is just a set of colour boxes, when SVG has a perfectly decent gradient format defined.

I was just actually showing a colleague perceptually uniform color scales just today!

This will come in very handy for me. Thanks for working on this and putting out there.

Does using a range of hues generate colors that can be differentiated by those of us who are color blind?

Careful, this is really not good for folks who are color blind. In chromium devtools you can enable various color blind emulations in the device emulation menu. ctrl+shift+P -> "Protanopia"

Hah, what a coincidence. I did small research today for heatmaps for my very simply graph lib for Ruby. I recommend this blog post:

https://research.google/blog/turbo-an-improved-rainbow-color...

I myself implemented 4 colorize functions for that. Common linear Blue -> Red. Linear Blue -> Red adjusted via Green for visibility. Blue -> Yellow -> Red also linear. And of course Turbo from that blog..

It is great but of course people are going to shit on it because what fun would it be without being negative.
