The color theory covers many definitions, ideas, and design applications that might fill multiple encyclopedias. The color wheel, color harmony, and the context in which colors are utilized are the three logical and practical core concepts of color theory.

THE COLOR WHEEL

1. Primary Color Wheel
   Red, yellow, and blue (RGB) are the primary colors.
   Primary colors are the three pigment colors that, according to conventional color theory (used in paint and pigments), cannot be combined or created by any other colors.
   These three colors are the source of all other colors.
2. Secondary Color Wheel
   Green, orange, and purple are the secondary colors.
   These hues result from combining primary colors.
3. Tertiary Colors
   Yellow-orange, red-orange, blue-purple, green-blue, purple-purple, and yellow-green
   These are the hues that result from combining a primary and a secondary hue. Due to this, colors have two-word names like blue-green, red-violet, and yellow-orange.

THE COLOR TYPES

1. Analogous Colors
   On a 12-part color wheel, analogous colors are any three hues that are next to one another, such as yellow-green, yellow, and yellow-orange. One of the three hues predominates more frequently.
   Uses colors that are next to each other on the wheel.
   
2. Complimentary Colors
   Any two hues that contrast sharply from one another are said to be complementary, like red and green, red-purple, and yellow-green. Several varieties of yellow-green may be seen in the leaves, and several red-purple hues can be seen in the orchid in the picture above. Maximum stability and contrast are produced by these clashing hues.
   It uses colors that are on opposite sides of the color wheel.
   
3. Natural Colors
