CONTROL
Colour controls:
Allow real-time control of colour, for both
colour modification
(colourizing)
o f live images, and painting.
The colour selection method follows the Hue, Saturation, Value
(H.S.V.) colour model.
The four controls in this group are:
i)
HUE:
This selects the actual 'colour' from the spectrum. The
slider is marked: RED YELLOW GREEN CYAN BLUE
MAGENT A RED, giving
a
full colour circle. It is a
continuous scale, so positioning the slider between, sa y, RED
and YELLOW will yield ORANGE.
i i)
SATURATION:
The satura tion of a colour is its 'purity'. For
insta nce, high saturation
red
is a bright red, decreasin g
saturation goes through various shades of pink, until at
minimum saturation, the result is
white.
This slider may be
regarded as adding 'whiteness' as the control is
dec reased.
iii) VALUE: This control affects the
brightness
of the colour. Fu ll
brightness occurs when the slider is at the top of its travel,
and moving the control down will darken the colour, u ntil at
the bottom it will be
black.
With value at black , HUE and
SATURATION sliders will have no effect, as you cannot
perceive colour in total da rkness.
iv)
COLOU R DEPTH:
This controls the degree in which the
H.S.V. colour in teracts with colour al ready on the screen. In
simple terms it is like a translucency control, or 'thickness' of
colour, but its actual effect depends on the selection made in
the COLOUR TYPE menu (or COLOUR I ZE TYPE menu for
colourizing).
