The Human Brain and Perception

The human brain is a complex organ responsible for our personality and experiences.
Our brains receive information from the world through our senses, and we perceive reality based on this information.
Neuroscientists recognize at least 20 senses that contribute to our perception of reality.
Our brains fill in gaps in sensory information by modeling or predicting what we think reality is.

Vision is a complex sense that involves the retina, a sophisticated computing device at the back of the eye.
Different people perceive colors differently due to variations in their visual systems, such as color blindness or tetrachromacy.
The dress phenomenon of 2015 revealed a fundamental difference in how people perceive colors.
Color is a shared illusion created by the biology of neurons in our retinas and brains, influenced by our sun's energy.
Our brains interpret the electromagnetic emissions from the sun, specifically the wavelength of photons, as colors.
The visible spectrum of light, which we perceive as colors, ranges from 400 to 700 nanometers.
Photo receptors in our retinas, called opsins, match specific wavelengths of light and correspond to the colors we perceive as blue, green, and red.
Our eyes evolved to capture light, and our photoreceptors act as biological antennas for photon energies between 400 and 700 nanometers.
Colors don't exist in nature; our brains perceive combinations of wavelengths that we associate with important things for survival, such as food and reproduction.

Each individual lives in a slightly different reality due to variations in sensory perception and processing.
Despite these differences, we generally agree on what reality is.
In a chaotic and divisive world, it's important to recognize the diversity of our experiences and default to compassion and kindness.
