Try changing the hue:
Press F1 (hue) five or six times .
Notice that each time you press and release the key, the color of the box changes
and the hue value changes - by 4° on the 4109 , and 10° on the 4106 or 4107. The
degrees indicate where you are in the color coordinate system.
Continue changing the hue:
Press and hold F1 .
The hue value continues to increase by set increments and wraps around to zero
when it passes 360°. You can watch the box on the screen go through the full
range of hues in concert with the change in hue values. Now, try this :
Press Shift-F1 (hold down the Shift key and press F1 ).
Note that pressing F1 increases the hue value and pressing Shift-F1 decreases the
hue value . You can change the lightness and saturation values in a similar fashion
with the F2 and F3 keys.
Table 2-1 shows what each Set Color function key does when you press it.
Experiment with changing HLS values by pressing Keys F1 , F2, F3 and their
shifted versions .
