The dots are white blood cells moving in the capillaries in front of the retina of the eye. [5] Blue light (optimal wavelength: 430 nm) is absorbed by the red blood cells that fill the capillaries. The eye and brain "edit out" the shadow lines of the capillaries, partially by dark adaptation of the photoreceptors lying beneath the capillaries ...
The red light reaches the observer's eye, whereas the blue light is scattered out of the line of sight. Other colours in the sky, such as glowing skies at dusk and dawn. These are from additional particulate matter in the sky that scatter different colors at different angles. Halos, afterglows, coronas, polar stratospheric clouds, and sun dogs.
Blue–red contrast demonstrating depth perception effects 3 Layers of depths "Rivers, Valleys & Mountains". Chromostereopsis is a visual illusion whereby the impression of depth is conveyed in two-dimensional color images, usually of red–blue or red–green colors, but can also be perceived with red–grey or blue–grey images.
Here's a breakdown of how and why it all happens. But the science behind a blue sky isn't that easy. For starters, it involves something called the Rayleigh effect, or Rayleigh scattering.
Mie scattering (Why clouds are white) Metamerism as of alexandrite; Moiré pattern; Newton's rings; Phosphorescence; Pleochroism gems or crystals, which seem "many-colored" Rayleigh scattering (Why the sky is blue, sunsets are red, and associated phenomena) Reflection; Refraction; Sonoluminescence. Shrimpoluminescence; Synchrotron radiation

A 2002 study found the prevalence of blue eye color among the white population in the United States to be 33.8% for those born from 1936 through 1951, compared with 57.4% for those born from 1899 through 1905. [15] As of 2006, one out of every six Americans, or 16.6% of the total US population, has blue eyes, [63] including 22.3% of whites.
