Introduction to colour

Definitions: 

Hue 

• An element of the color wheel
• One of the main properties of a color
• Refers to a pure color in painting color theory - one without tint or shade

           http://en.wikipedia.org/wiki/File:HueScale.svg

Value

• Lightness or darkness of color, sometimes called tone.
• A property of a color or a dimension of a color space.
• More white to hue, brighter the value; vice versa

Saturation

• Colorfulness of a color relative to its own brightness
• Related to colorfulness and chroma in colorimetry and color theory
• Purity of a hue
• The more the gray a color contains, the less saturated it is

 Secondary Color

• Mixture of two primary colors in a given color space.
• Red and yellow = orange, yellow and blue = green, red and blue = purple.
• Depends on the proportion in which you mix the two primaries.

Tertiary color

• A tertiary color is a color made by mixing either one primary color with one secondary color, or two secondary colors, in a given color space such as RGB ( more modern ) or RYB ( traditional ).
• RYB uses pigments, similar to CMY, which combine subtractively by absorbing light. Thus, combining colors using the RYB system will result in a darker color.
• Additive secondaries - Light (RGB)

• red	(●)	+	green	(●)	=	yellow	(●)
  green	(●)	+	blue	(●)	=	cyan	(●)
  blue	(●)	+	red	(●)	=	magenta	(●)

  
  
  
• Subtractive secondaries - Pigment (CMY) [CMYK's "K" stands for Key (usually black)]

  	cyan	(●)	+	magenta	(●)	=	blue	(●)
  	magenta	(●)	+	yellow	(●)	=	red	(●)
  	yellow	(●)	+	cyan	(●)	=	green	(●)

• Traditional painting (RYB)
  

  RYB colors: primary (roman) and secondary (bold)

  yellow

  orange

  red

  purple

  blue

  green

  yellow

Analogous color

• Analogous colors are groups of colors that are adjacent to each other on the color wheel, with one being the dominant color.
• Which tends to be a primary or secondary color, and two on either side complimenting, which tend to be tertiary.

Tint

• A tint is the mixture of a color with white, which increase lightness.

Shade

• A shade is the mixture of a color with black, which reduces lightness.
