From Aristotle's era, great thinkers have questioned about the different nature of reality, how the concept works, and how humans see it. The basic principle of color is such a mystery. As an unstable property, the secret of color has plagued philosophers, artists and scientists for centuries until Sir Isaac Newton discovered the attribute of light in 1666. Thanks to the foresighted people such as Newton, Hermann von Helmholtz and Georges Suura, the understanding of the color of contemporary people can be explained in different ways and now it can be classified by media I will.
Before understanding color blindness, it is important to understand that color vision is a function of the brain's ability to explain the complex way light is reflected from each object. "Perception of color is related to the physical properties of wavelengths" (Goldstein, 2010, p. 204). Red, green and blue are the three primary colors, each color reflects a specific wavelength. The eye uses these three colors - this means that the retina of the eye absorbs a mixture of these colors. Behind the retina there are three photoreceptor cones (L, M, S) that cause the color differences we see. Each cone is associated with one of the three primary colors by its wavelength. For example, red (long), green (medium), and blue (short).
The most basic way to master color psychology is to first understand the color wheel. The color wheel consists of 1, 2, 3 hues of hue, hue, hue, hue. The primary colors are yellow, blue, and red. At the same time, secondary colors include green, orange and purple. These colors are the main colors used in branding and advertising. Bold primary colors are often used for brand identity (logo). They gather attention from the audience and they become easier to identify if they are used for a long time. This is due not only to the brand name but also to the brand color. For example, the next logo displayed in the photo uses the basic color, but uses a minimal front and negative space (white and black representation) for branding. (Note: In this article, black and white is described as "real" color, but it is not considered as color of design.
