    So there is a lot of work on this in color theory, and you can go deep into this… Here are a few chapters on the matter: https://slcc.pressbooks.pub/maps/chapter/9-2/ , https://courses.ems.psu.edu/geog486/node/876 , and this part in particular https://courses.ems.psu.edu/geog486/node/877

    Basically, their use of brightness within hue bins makes this a non-function. Notice how its gets whiter closer to 0 and closer to 13. If two values of Y can get plugged into a function and they both return 0 for the expected X term, thats a non-function.

    Temperature, or rather, difference in temperature from expected, which is whats being plotted here, is about divergence from normal.

    To fix this map, pick a divergent color scheme, center 0, then create bins at either a specific interval or at quantile intervals.

    Something like this: https://colorbrewer2.org/#type=diverging&scheme=RdYlBu&n=11

      While I do appreciate the information on better infographic creation, the example map has such a small range comparably. There’s over 30 values, not to mention the shades in-between values. I think a two color gradient would end up being very smooth at this scale. Sorta looks to generally drop in temperature as you go east here, nice red to blue fade.

      Expanding the color palette does give more room for distinction, but that’s seemingly how they got where they did.

      To be fair, from my friends who’ve actually had color theory and graphic design classes, STEM folks tend to do a poor job of communicating well.

      So eh. Maybe it’s pointless for me to argue against it.

        To be fair, from my friends who’ve actually had color theory and graphic design classes, STEM folks tend to do a poor job of communicating well.

        it’s a way of thinking about your audience, i think. when i worked in accounting and had to present to and teach accountants: simple formatted tables, stuff that looks like excel, it didn’t need to be bright or colorful. it just needed to have colors that were unobtrusive. i’m working in music now and if my seminars don’t have showmanship (and if i use powerpoint at all) i’m hosed. different audiences have completely different styles that they are used to communicating with, and if you adapt to that you’re going to have more success

        so like, i’m sure the STEM folk are fine at communicating within their field. outside? well, a few of my uncles were engineers. does it show?
