Newbie here with possible strange request.
I am learning anatomy, currently by studying a 3d skull.
I would like to lit it in some ways, so that the faces facing front would be in a certain color, the faces facing left in another, the faces facing right in another.. you get the idea.
This would come with some threshold i guess: lit faces that are x degrees facing front for example.
I guess that i would have to dig into creating a shader to do so? Maybe with the normals?
Maybe what i want is not possible?
Thanks in advance!

If you want it to look like lighting, you could just use colored lights?
But to shade the surface, you could use an arrangement something like this ..
.. which is quite tweakable .. It would depend.. how do you want the colors to be combined.. as @moonboots asked, do you want the colors to be stuck to the surface?

Here is a similar setup then Robin Betts, but a little bit more complex/ parametric:
1: Mapping-Location changes offset (values from 0 - 1)
2: Mapping-Scale changes blur/sharpness (values from 0 - 100)
This way all the directions are equally separated
After some further experimentation, i found it to be quite tricky to not only mix colors, but to use the resulting colors as sharp masks. Therefore here an alternative version wich uses the resulting mixed-color green as Mask.
In this case only green is masked

There are a couple ways to do this. If you just want to view the 3d skull, you can just turn on a matcap, which will shade objects in the viewport in different ways that make it easier to see the geometry. There are two ways I can think of to render the skull. One is to create a shader. Another is to just set a couple differently colored lights in the scene that shine on the skull from different angles, making it easier to see, or imitating the effect you might get from a shader.
