Operation
Color: On your external test pattern source, select a color bar pattern like the one shown
in Figure 4-4.
Figure 4-4. Typical Color Bar Pattern for Adjusting Color Saturation and Tint
Select Color from the Picture Adjust menu and press ENTER. While looking at the color
bar pattern through a blue filter, adjust the color saturation level until the outermost (gray
and blue) color bars appear to be a single shade of blue:
Tint: Tint or "hue" is essentially the ratio of red to green in the color portion of the image.
When tint is decreased, the image appears redder; when it is increased the image
appears greener. To set the tint, select Tint from the Adjustment menu and press ENTER.
While looking at the color bar pattern through a blue filter, adjust the tint level until the cyan
and magenta color bars (on either side of the green bar) appear to be a single shade of
blue.
