Texture
- Color Workbench provides
Color and Texture menu. User can do color and texture management
in this workbench.
- Some command uses HLV
and HLS system for color definition
- Definition of HLV
color system
The
Hue/Saturation/Value model is based on such intuitive color characteristics
as tint, shade and tone (or family, purity and intensity).
The coordinate system is cylindrical and the colors are defined inside a
hexcone. The hue value H runs from 0 to 360¨¬.
The saturation S is the degree of strength or purity and is from 0 to 1.
Purity is how much white is added to the color, so S=1 makes the purest
color (no white).
Brightness V also ranges from 0 to 1, where 0 is the black.

- Definition of HLS
color system
Hue:
the
attribute of color by means of which a
color is perceived to be red, yellow,
green, blue, purple, etc. Pure white, black and grays possess no hue (Range
0 to 360¡Æ)
Lightness:
(1) the
attribute of color perception by which a
non-self-luminous body is judged to reflect more or less light. (2) the
attribute by which a perceived color is
judged to be equivalent to one of a series of grays ranging from black to
white (Range 0 to 255).
Saturation:
the attribute
of color perception that expresses the
degree of departure from the gray of the same lightness. All grays have zero
saturation. Commonly used as a synonym for chroma especially in graphic arts
(Range 0 to 255).
Lightness and saturation may still be somewhat confusing. An alternative
definition for lightness is the amount of white contained within a
color whereas the amount of gray defines
a color's saturation. Fully saturated
colors contain no gray. All grays including black and white are not
saturated.
