value of 64 allows you to view the image at a minimum luminance.
Modifier 2: Scales the x chrominance component. The default DMX value of 128 (50%) = no
adjustment. Values below the midpoint scale the x chrominance component down as you
approach 0 = minimum. Values above the midpoint up to a maximum. at a value of 255 (100%)
Modifier 3: Scales the y chrominance component. The default DMX value of 128 (50%) = no
adjustment. Values below the midpoint scale the y chrominance component down as you
approach 0 = minimum. Values above the midpoint scale the y chrominance component up to a
maximum at a value of 255 (100%).
