Tim,
1 = 1 bit color = 2^1 = 2 colors
4 = 4 bit color = 2^4 = 16 colors
8 = 8 bit color = 2^8 = 256 colors
24 = 24 bit color = 2^24 = 16 million colors
LabVIEW doesn't support 16/32 bit colors.
Default is 8 bit.
There is no 2 bit. Greyscale means red component
equals to green component and blue component.
Greyscale color depth can be 1, 4, 8, or 24 bit.
Color depth greater than 8 bit usually doesn't have
a color table. These thing are defined by the system,
not NI.
