Therefore, the luma, analog voltage, and luminance of each color is as follows, when a standard
color bar is displayed:
Display Color (R/G/B)
White (255/255/255)
Yellow (255/255/0)
Light Blue (0/255/255)
Green (0/255/0)
Purple (255/0/255)
Red (255/0/0)
Blue (0/0/255)
Black (0/0/0)
The preceding calculations assume that the programmer has selected a gamma (γ) of 1.0, as
recommended in the section "Gamma Correction" in the Revolution Graphics Library, contained in
your Revolution SDK. If a different gamma is selected, it must be accounted for in the formula:
