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.
