Properties of colour
Hue: Hue is pure colour - any primary, secondary or tertiary colour that is unmixed with black or white. It can be another name for colour.

Reflective Value: This is the degree of lightness or darkness of a tint, shade or tone. White has the highest reflective value and black the lowest.

Tint: A tint is the pure colour (hue) with white added. This new colour has higher reflective value (is lighter) than the original hue.

Shade: A shade is the pure colour (hue) with black added. This new colour has a lower reflective value (is darker) than the original hue.

Tone: This is pure colour (hue) with grey added. This new colour is a softer variation of the original.

Intensity: This is brightness or dullness of colours. Less intense colours (blue) have a calmer effect and are easier to live with than the more intense colours (red). Intense colours are often used as highlights and contrast.
