OK a 400nm LED looks slightly purple to human eyes, but that's not because it's a mix of blue and red light, correct? If that's the case, then presumably they only trigger the blue sensors in a digital camera, so why do pictures of these LEDs appear purple? This can only be because my monitor is showing me both blue and red light, correct? Does the color processing of the camera or computer decide to make it purple instead of blue?
