Color Wheel

Modern thinking is that there are 4 basic colors, Blue, Red, Green and Yellow, and every other colour used in paint and other decorations are variations of these four (and also black and white which are not considered as colors). Although our Color Wheel has just 12 colors, the colors vary continuously around the wheel with millions of possible shades. Each colour is associated with a perception and their use can affect the way people feel and act - so the choice of color in decorations needs to take into consideration the nature of the area being decorated.

Hue

Hue, saturation, and brightness are aspects of color in the red, green, and blue (RGB) scheme. These terms are most often used in reference to the color of each pixel in a cathode ray tube (CRT) display.

All possible colors can be specified according to hue saturation, and brightness (also called brilliance), just as colors can be represented in terms of the R, G, and B components. In hue there are three types of colors primary,secondary, and tertiary.

Primary colors

There are three primary colors: red, blue, and yellow. They are called primary colors because mixing other colors cannot create them. Primary colors form the basis for color theory or color mixing, as using these three colors it's possible to mix most other colors.

Secondary colors

They're located in-between the primary colors to indicate what colors they're made from. Secondary colors are colors produced by combining two of the primary colors in equal amounts. The secondary colors, also called binary colors, are violet, green, and orange.

Tertiary colors

Tertiary colors are combinations of primary and secondary colors. There are six tertiary colors; red-orange, yellow-orange, yellow-green, blue-green, blue-violet, and red-violet.

Tint

The light tones resulting when white are mixed with a color. Much white makes a color cold.

Shade

The shade of a color refers to how dark it is. It is the combination of a hue and black. Shades of a color offer a deeper and richer feeling in decorating and can be used to make any room feel cozier.

Tone

Tones are created when grey is added to colors. Adding grey results in colors that are less intense versions of pure colors.
