>According to my settings tab both 24 and 32 bit color are referred to as "True Color" and 16 bit is "High Color". I'm using 32 bit on the machine and made the assumption based on its reading that the next lowest would be "High Color". Thanks for the heads up.

The normal use is that High color is either a 15 or 16 bit color setting, and True color is any 24 bit or higher color depth.
