3 For Hue, enter a value or drag the slider until the
colors appear as you want.
The values displayed in the text box reflect the
number of degrees of rotation around the wheel
from the pixel's original color. A positive value
indicates clockwise rotation, a negative value
counterclockwise rotation. Values can range from
-180 to +180.
For Saturation, enter a value or drag the slider to
4
the right to increase the saturation, left to decrease
it. The color shifts away from or toward the center
of the wheel, relative to the beginning color values
of the selected pixels. Values can range from -100
to +100.
For a color illustration of saturation, see
figure 6-5 on page 226.
5 For Lightness, enter a value or drag the slider to
the right to increase the lightness, left to decrease
it. Values can range from –100 to +100.
To modify the range of an adjustment slider:
1 Choose an individual color from the Edit menu
in the dialog box:
2 Do any of the following to the adjustment slider:
Drag the dark gray, center part to move the
•
entire adjustment slider, selecting a different color
area.
Drag one of the vertical white bars next to the
•
dark gray, center part to adjust the range of the
color component. Increasing the range decreases
the fall off, and vice versa.
Drag one of the lighter gray bars to adjust the
•
range without affecting the amount of fall off.
Drag one of the white triangles to adjust the
•
amount of fall off, without affecting the range.
Ctrl-drag (Windows) or Command-drag
•
(Mac OS) to drag the color bar, so that a different
color is in the center of the bar.
If you modify the adjustment slider so that it falls
into a different color range, the name changes to
reflect this. For example, if you choose Yellow and
alter its range so that it falls in the red part of the
color bar, the name changes to Red 2. You can
convert up to six of the individual color ranges to
varieties of the same color range (for example, Red
through Red 6).
Note: By default, the range of color selected when
you choose a color component is 30° wide, with 30°
of fall off on either side. Setting the fall off too low can
produce dithering in the image.
3 To edit the range by choosing colors from the
image, select the eyedropper tool ( ) in the dialog
box and click in the image. Use the eyedropper +
tool to add to the range; use the eyedropper - tool
to subtract from the range. (While the eyedropper
tool is selected, you can also press Shift to add to
the range or Alt (Windows) or Option (Mac OS)
to subtract.)
For a color illustration of hue change, see
figure 6-6 on page 226.
