But since, as he stated immediately before, "light waves enter the eye
and are converted to electrical impulses in the brain," the wavelength
of red (or any other color of) light never reaches the hypothalamus
(unless you were to shine a VERY bright one at the roof of your mouth).
The neural "coding" for color isn't a direct reflection of the light's
wavelength. It is the relative pattern of impulses coming from the three
different kind of color-sensitive photoreceptors in the retina
("cones"). All that reaches your hypothalamus (apart from high-speed
projectiles) are the same electrical impulses that rattle around the
rest of your brain.
Oh, and just tot play along for a minute, because red has a long
wavelength (low frequency), it is also a low-energy part of the visible
spectrum. Violet is at the high-energy end. That's why ultra-violet can
disrupt your skin cells causing burns a, sometimes, cancer.
The things people can make money saying. :-)
