"I Want Hue" – Colors for Data Scientists

Re: "I Want Hue" – Colors for Data Scientists
#2This is an interesting tool, it fails at 16 colors. Which is surprising. (it may be the gamut of my display of course but I would think 16 would be within its abilities). That is probably the most number of distinct colors I've needed in a graph. Works nicely for numbers 10 and below.

#3Aw, so sorry to tell you but it doesn't work in the latest version of IE. I'm not even sure if you should bother trying to get it to work but at minimum just put up a message to IE users telling them to use another browser.

#4Love this, even just for website palettes. Nice work.

#5I'm glad it's not a Mordekaiser circle jerk.

#6This is really nice! And attractive.
One of the reasons I'll probably stick with ColorBrewer palettes for now is that I can easily find color schemes that are safe for people with colorblindness or for display in particular environments.

#7I've used something similar in matlab, which I though worked a little better. It started out with red green blue, colors frequently considered maximally distinct, at least on color monitors for the non-colorblind. Then it just found maximally distant points in the color cube. I found it worked nicely and you could also seed it with your own starting color(s).
Edit: found out it is based on Lab color space.

#8Great tool, it heavily uses chroma.js

The HCL color space is also available in this d3 module: https://github.com/d3/d3-plugins/tree/master/cie

#9I really like the interaction and flexibility, but I failed to generate a set of colors as nice as those provided by Color Brewer (http://colorbrewer2.org/). Sure, Color Brewer doesn't dynamically generate color schemes, but the set of colors it provides looks damn good in just about any context. I might use this new app in cases where I need more than 12 colors (Color Brewer's limit), but I don't think dynamic color scheme generation adds much. The JSON and CSS exports do seem very useful, however, and a big improvement over Color Brewer's interface.

Hmm...the linked page worked for me on several tries for 16, 20, and 22 colors, even restricting the luminance somewhat.
I used the protovis categorical colors (http://mbostock.github.com/protovis/docs/color.html, see at the bottom of the page) when I needed a 20-color map recently.
