The human eye's red-to-green and blue-to-yellow values of each one-wavelength visible color [citation needed] Human color sensation is defined by the sensitivity curves (shown here normalized) of the three kinds of cone cells: respectively the short-, medium- and long-wavelength types.
Since the blue waves become separated from the rest of the light spectrum through this scattering effect, that's what we see with our naked eyes. And we see the blue light instead of violet light ...
An example of this phenomenon is when clean air scatters blue light more than red light, and so the midday sky appears blue (apart from the area around the Sun which appears white because the light is not scattered as much). The optical window is also referred to as the "visible window" because it overlaps the human visible response spectrum.
Today, among simians, the catarrhines (Old World monkeys and apes, including humans) are routinely trichromatic—meaning that both males and females possess three opsins, sensitive to short-wave, medium-wave, and long-wave light [4] —while, conversely, only a small fraction of platyrrhine primates (New World monkeys) are trichromats.

This is followed shortly by Haidinger's brush." He commented that not all observers see it in the same way. Some see the yellow pattern as solid and the blue pattern as interrupted, as in the illustrations on this page. Some see the blue as solid and the yellow as interrupted, and some see it alternating between the two states.
Beachgoers watch and record images of bioluminescent waves breaking in Huntington Beach on Jan. 2, 2024. Bioluminescence is light emitted by living things through chemical reactions in their bodies.
As humans typically exhibit three classes of cones, cone monochromats can hypothetically derive their photopic vision from any one of them, leading to three categories of cone monochromats: [4] Blue cone monochromacy (BCM), also known as S-cone monochromacy, is an X-linked cone disease. [ 5 ]
A pungent, fishy odor has been wafting through the air by Los Angeles' shore this week, an unfortunate consequence of beautiful bioluminescent algae.
