    Nope. Purple is a wavelength that partially triggers both the red and blue cones.

    The visual spectrum is continuous, not just three wavelengths corresponding to the three cones.

    The blue cones and the red cones are stimulated by purple light. It’s a mix of blue and red signals from the retina, but the light is a single wavelength that is actually purple.

      No, purple is a non spectral colour meaning it is incorrect to call it “a wavelength” but rather you say it is a perception of multiple wavelengths. Not that this is special, pretty much everything you see is a non-spectral colour.

        This is the best in depth scientific explanation here, and deserves more upvotes. Thanks, was a nice read!

      Purple is a green wavelength that doesn’t trigger the green cones in your eyes.

      It is made up by your brain.
