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.
