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.
