    How would you suggest they do that. White light near equally activates our 3 cones because all spectrums of light are in it.

    White light near equally activates all 12 shrimp cones because all spectrums of light are in it.

    Which spectrum of color is left out of white light that wouldn’t light up a cone associated with it?

      Because white light from an LED bulb is not all spectrums of light. It’s 3. It’s pure red, pure green, and pure blue that stimulates our cones equally so our brain can’t tell the difference. Like how TVs can make any color out of just three colors of sub pixel.

      White light from an incandescent bulb is all spectrums of light. Through a prism it makes a rainbow. White LEDs through a prism make three stripes. For more information of this and some visuals check out this article. https://en.wikipedia.org/wiki/Color_rendering_index
