Hue
Hue identifies the general family of a color, such as red, yellow, blue or green. The traditional color wheel is made up of twelve color families: red, red-orange, orange, yellow-orange, yellow, yellow-green, green, blue-green, blue-red-violet, violet and blue-violet.
Color Wheel
Colors on the opposite side of the wheel from each other are called complementary colors. In combination, these create striking contrasts. For less contrast, choose colors next to each other on the color wheel, which are called analogous colors. Choosing colors of different tints within in one color family creates a monochromatic color scheme.
Warm or Cool?
Different colors in the same family may be described as being "warm" or "cool." Colors with yellow undertones will seem warmer, while the same color with blue or red undertones will appear cool. Cool colors - blue, green, violet - invite relaxation and thought. Warm colors - red, orange, yellow - encourage conversation and play. color experts suggest using both warm and cool colors in rooms where you desire balance and variety.
Value
Value describes how light or dark a specific color may be. It’s easy to use lighter colors towards the ceiling or on it, middle and darker values on walls or towards the bottom. When you combine the same hue in varied values you're creating a monochromatic color scheme - perfect for creating a sophisticated, spacious look in a single room.
The Color Wheel

A color circle, based on red, yellow and blue, is traditional in the field of art. Sir Isaac Newton developed the first circular diagram of colors in 1666. Since then scientists and artists have studied and designed numerous variations of this concept. Differences of opinion about the validity of one format over another continue to provoke debate. In reality, any color circle or color wheel which presents a logically arranged sequence of pure hues has merit.

PRIMARY COLORS
Red, yellow and blue
In traditional color theory, these are the 3 pigment colors that can not be
mixed or formed by any combination of other colors. All other colors are derived from these 3 hues

SECONDARY COLORS
Green, orange and purple
These are the colors formed by mixing the primary colors.

TERTIARY COLORS
Yellow-orange, red-orange,red-purple,blue-purple, blue-green
and yellow-green.
These are the colors formed by mixing one primary and one secondary color.
