The
HSV color space
The HSV color space is very similar
to the HIS color space. In HSV every color is represented by three
components Hue ( H ), Saturation ( S ) and Value ( V ).
The following figure shows how this
color model represents each color in a six sided pyramid form.
The Hue component describes the color
itself in the form of an angle between [0,360] degrees. 0 degree
mean red, 120 means green 240 means blue. 60 degrees is yellow,
300 degrees is magenta.
The Saturation component signals how much the color is polluted
with white color. The range of the S component is [0,1].
Black has a V coordinate of 0. At this
point the values of H and S are irrelevant. The point S=0, V=1 is
white. Intermediate values of V for S=0 (on the center line) are
the grays. When S=0 value of H is irrelevant (called by convention
undefined). When S
is not zero, H is relevant. For example pure red is at H=0, S=1,
V=1.
The formula that converts from RGB
to HSV or back is more complicated than with other color models,
therefore we will not elaborate on the detailed specifics involved
in this process.
