I'd like to mix the colors to get the exact color that you would get in reality, I realize that RGB is a completely different system, but I was wondering if anyone has experience with this. In the picture obviously I get the White being an RGB system is very obvious. I'm trying to study this a bit but I don't know if I'm on the right way

Further clarification: I would like to get the colors that would be obtained in reality (I think by subtractive synthesis) but I don't know this study very well, and I'd like to create a node that does this

enter image description here

  • $\begingroup$ Your node setup is most likely not what you wanted, to get "white", the right mix node will have to have a value of 0.666. Other than that, could you give us more insight of how colors are mixed in reality? What would mixing red and blue give e.g. $\endgroup$ – Leander Nov 24 '19 at 19:44
  • $\begingroup$ @Leander Hi, maybe I'll explain myself, white is obtained by mixing RGB colors, this is clear. I would rather get the colors that are obtained in reality as if they were mixing 3 real paints of that color $\endgroup$ – Pastrokkio Nov 24 '19 at 19:48
  • $\begingroup$ @Leander I think you should get a shade very close to black, more on brown, but I'm not a specialist in this studio, so I'd like to learn how to do something like this $\endgroup$ – Pastrokkio Nov 24 '19 at 19:52

    $\begingroup$ Read this? What is your actual end goal. Why is just picking a color not a good option? $\endgroup$ – Leander Nov 24 '19 at 19:58

    $\begingroup$ What you want is the multiply mode of the MixRGB node. You will notice though, that multiplying red and blue will result in black. This would happen in real life as well if your colors were pure red and black. But in real life, colors contain a range wavelengths and are already mixes themselves. You can't simulate that with simple RGB inputs. $\endgroup$ – Leander Nov 24 '19 at 20:05
