In terms of the color of the skin, many people assume that they actually have a particular colored pigment in our irises (a coloring feature of our eyes).
Have you ever heard about the influence of Tyndall? It is the term used for the purposes of explaining the dispersion of light by small suspended particles, named after John Tyndall, a 19th-century physicist. As light is distributed, various colored wavelengths are formed with each wave frequency and the wavelength being different. It’s why our skies are blue and why we almost see something similar every day: blue eyes.
As to eye color, many people believe like they have various colored pigments in our irises (the colored component of our eyes) that produce all the different eye colors we see. In reality, the truth is a lot cooler.
The iris consists of two layers, the epithelium on the back and the stroma in the center. The epithet is about two cells long, with pigments in black or brown.
The front layer of the stroma may consist of collagen or a dark pigment known as melanin. People with black or brown eyes appear to have more melanin than people with green or blue eyes. Their fore and rear layers are colored with dark pigments.
People with blue eyes have what is called “Structural coloring,” which means that their eyes have no color in them, which means that it is simply transparent or white. The color of their eyes depends entirely on this. The layer of epithelium behind the stroma is dark enough that it absorbs most of the longer wavelengths of light, which only creates the shorter wavelengths of light that bounce back outward–producing the blue shades we all see.
Any light that reaches a transparent iris, due to the thin suspension of particles in the pupil, or the Tyndall effect, is disseminated outside. And your eyes are not always blue if you have brown hair. They are colorless, and you feel blue by the manner in which luminous particles in your stream communicate with you.
” Such a phenomenon is profoundly depicted by Paul Van Slembrouck. It comes from the structural coloration and there are slippery muscle tissue fibers in meshing that seem to stretch the pupil and push the inner rim of the iris towards its outer rim. As this happens, stroma fibers slacken and may become wiggly with the release of stress. That’s why I wonder, doesn’t that affect your eye’s color?” Nearly every eye looks different, depending on current light levels and tube form. Many structural colors are commonly present such as birds, beef and other berries.
