Color theory is both a science and an art form. It describes how people see color and the visual consequences of colors mixing, matching, or contrasting with one another. Color theory also includes the signals that colors convey as well as the methods utilized to recreate color.
There are many theories about what makes up color. The most common theories include physical properties of light such as red, green, and blue which make up all colors; psychological effects of light on the eye such as brightness and saturation; and finally, cultural associations between colors and feelings such as pink for love and white for purity.
Physical properties of light: The quality of light varies depending on the time of day and the location where it is seen. Light is made up of waves called photons which have different frequencies depending on the height above sea level they reach. Photons of high frequency (short wavelengths) are blue, while those of low frequency (long wavelengths) are red. Between these extremes are other colors which can be produced by combining photons of different frequencies. For example, yellow comes from combining photons of high and low frequency. Because photosites in our eyes are more sensitive to some frequencies of light than others, we perceive colors that don't actually exist. For example, photosites are less responsive to blue light, so we see red instead. Similarly, photosites are more responsive to red light, so we see yellow instead.
Color Theory is the art of blending certain colors in a way that is harmonic, or just looks good together! ... There are many different theories on how colors work together to create beauty, and over time many color theories have been developed.
In photography, there are two main types of color theories: analytical and perceptual. Analytical color theories use scientific methods to break down colors into their constituent parts, determine which parts interact with each other, and then put them back together in new combinations. These theories can be very accurate but they are also difficult to apply because no single color can be separated into its components completely without losing some information about it. As a result, analytical color theories often give highly specific instructions on how to combine colors in order to get desired results.
Perceptual color theories try to describe what qualities people see when they look at colors together, then use that knowledge to blend colors in ways that will make them appear more beautiful. These theories are not based on science so they can't be proven wrong like analytical theories can but they can also say something incorrect about colors that scientists later discover through testing.
At the end of the day, both types of theories can be useful tools for photographers to know about when trying to achieve certain effects.
Color theory is a form of coding, similar to HTML, that computers employ to show colors graphically. Just as with HTML codes, colors can be assigned numbers that describe how they should be displayed on a screen or printed page. These numbers are called RGB values.
The science of color has many theories and models that explain how the eye perceives color and how these perceptions influence our emotions and judgments. The theories and models help paint a comprehensive picture of how color affects us so that we may better utilize it in our designs.
Color theory has been used by designers for thousands of years. The ancient Egyptians invented color theory as we know it today. They divided colors into three categories: white, black, and other colors. By mixing combinations of these three primary colors, they were able to create almost any color you can think of. Modern color theorists have improved upon this technology by adding more primary colors and developing new ways of combining them.
Color theory serves two main purposes in design. First, it helps determine what colors will look good together. Second, it allows for subtle changes in color schemes over time or between projects.
