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
Picture Adjust 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.
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.
