#TweakThursday 29: Ordering by Color Warmth

In convention, warm colors correspond to higher numbers while cool colors to lower numbers. So when we assign colors to numbers, we do it according to color warmth.

Today's Viz of the Day (on 2/21/2017) shows the immigration distribution in all Swiss cantons. It's a very good design except that the coloring is kind of reversed. The higher rates are assigned cool colors and the lower rates are assigned warm colors. This confused me initially.

I would have tweaked the viz according to the color warmth. But unfortunately, the workbook is not downloadable.

That's the tweak of the day.
