COLOR SET-UP CONTROLS
The colors of the font and audio bar graphs are controlled by this set of controls. The luminance values
adjust, not only, their associated grey levels but also the luminance levels of a color. The following table
shows the relationship between the control and what it affects:
Luminance

White
Bar Graph
Border
The numbers used here represent decimal 8 bit values of the 4:2:2 video standard. For instance peak
white is represented by 235 (EB hex) which is ¼ of the 10 bit number of 940 (3AC hex).
When the luminance or color level control is selected, you are taken to a screen that allows you to observe
the changes that you are making.
