Color Saturation: 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. 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 Picture Adjust menu. 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.

Like the brightness and contrast controls, the color and tint controls are

interactive. A change to one may require a subtle change to the other in

order to achieve the optimum setting.
