Hue, Saturation, Value

Akronim: HSV

HSV
Hue, Saturation, Value.HSV is a way of defining a colour based on a colour
wheel. Hue measures the angle around the colour wheel (red is at 0 degrees,
green at 120 degrees, blue at 240 degrees). The saturation indicates the
radius on the colour wheel so indicates the proportion between dark (center)
to pure colour to white (outside). Value indicates the brightness.
Hue has a value between 0 to 360 (degrees), saturation and value range
from 0 to 100%. It is important to appreciate that different coding schemes
may use different representations, for example hex values from 0 to 0xFF to
represent hue.
An alternative way of understanding HSV is from the perspective of mixing
paints: Hue would represent the pigment, Saturation the amount of pigment
and Value the amount of white.
HSV is also known by the alternative HSB (Hue,
Saturation, Brightness).Relevant links:
