Appendix B

Hue, saturation and brightness

The color that we perceive with our eye is

composed of three elements: brightness, hue

and saturation. Bluebox World allows specific

foreground objects to be selected by making use

of all three criteria:

Hue:

Hue refers to a specific color from the spectrum

of all existing colors, without considering

brightness or saturation. Hue therefore defines

the left pure color content, starting with the

three basic colors red, green and blue, and

continuing through if all the intermediate colors

(orange, yellow, purple or magenta).

Color saturation:

The strength or emphasis of a hue is referred

to as the saturation. In any hue appears more

intense as its saturation rises. In the opposite

direction, a hue becomes paler as the saturation

is reduced, until finally only grey remains

without any color information.

Brightness:

The brightness determines the luminous power

of a specific hue having a specific saturation.

100% brightness generates white, 0% produces

black, while 50% brightness corresponds to the

pure hue.
