There is no actual Muller formula though. Though, I can see how you would build a color scale creator using the idea. I will see how it works with our data visualizations, and if so, d3 now has modules, I can build something for that.<p>Currently we use I Want Hue (<a href="http:&#x2F;&#x2F;tools.medialab.sciences-po.fr&#x2F;iwanthue&#x2F;" rel="nofollow">http:&#x2F;&#x2F;tools.medialab.sciences-po.fr&#x2F;iwanthue&#x2F;</a>) which works far better then it should :).
