Orange,violet and yellow have different frequencies. How can we see them, as we have only three receptors rgb?
Merely combining those frequencies cannot generate a new one.

1$\begingroup$ This question has rather detailed answers in the physics community. In a nutshell - they don't see other frequencies, but rather the color is determined by our brain by the relative excitation of different cones. $\endgroup$– Roger V.Commented Jul 30, 2021 at 10:32

$\begingroup$ How does your compute display create all sorts of colors when it has only 3 colors of pixels? $\endgroup$– jamesqfCommented Jul 30, 2021 at 15:43
