I was working on the project regarding the rift system, also at the same time earthquakes in Turkey and Syria happened, so somehow naturally I drifted towards tectonics, and tectonic plates and thought that it would be interesting to make the 'exploded view' of the tectonic plates. So we can say that those hot colors are also true colors :))

So what I did - I simply used black body color spectrum based on its temperature.

I was jumping back and forth with those colors, but when I saw Earths internal temperature graph somewhere and because it was in Kelvins somehow 'connecting the dots' moment happened and I realized that there is also the color spectrum for black body based on its temperature in Kelvins known. I was struggling to find the nice balance for these red and yellow colors, how do I show it properly, how do I show one sphere hotter than other, but then again making sure they are all well visible.

I had an idea of showing half of it as hot-red and another part as 'cooled down'. It's just the very basic, most common numbers and facts about the Earths structure illustrated but in slightly different perspective, to raise the curiosity and questions of What and Why?īy the way, interesting thing. And the deeper you go the more theory based all is. In this illustration there is no representation of convection, plumes or subduction slabs. I am fully aware that the internal structure, thus colors are not that obvious and simple. So the green-mantle illustration idea was born long time ago :)). And at the same time I found it interesting that most of Earths structure illustrations show red-hot-glowing spheres and there's no clue about parts of it being green. Years ago, probably in my first years of studying geology, when I learned that huge part of Earth's mantle is olivine-green I was amazed by that fact.
