Selecting a Color Area in the Color Wheel
The mouse pointer turns into a cross when it is in the color wheel. Drag the mouse pointer in the color
wheel to create a frame of any shape in it. After you release the mouse button, the area enclosed by the
line is then the selected color area. The following options are also available:
 Increase/add area:
SHIFT+drag the cursor to define more than one area or increase the size of an existing area. A
plus sign appears next to the mouse pointer. Simply encircle the area to be included keeping the
mouse button pressed.
 Reduce area:
If you press
ALT, a minus sign appears next to the mouse pointer. To cut out one or several areas
within a color selection, simply encircle the area to be deleted keeping the mouse button pressed.
 Select subset:
With the
ALT and SHIFT keys pressed, you can specify the overlap of two intersecting areas.
 Delete selection:
Double-click the color wheel to delete a color selection, or simply define a new area.
The current color (at the mouse pointer) appears in numeric format as an RGB (red-green-blue) and
HLS (Hue-Lightness-Saturation) value below the color wheel.
Luminance Range
The vertical line on the left of the spectrum is used for setting the luminance key. Values in the range of
the white sliders are in the key range; those outside the range of the black sliders are outside of the key
range. The areas between the white and black sliders represent transitional areas. The closer the sliders
are together, the narrower the luminance area that will be keyed.
A double-click on or close to the vertical line resets the sliders to their initial positions.
Softness
Use Softness to create a soft transition between key and foreground.
Spill Suppression
Use Spill Suppression to desaturate and thus make less visible any existing color values of the key color,
especially at the edges of the foreground.
