    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.
