Looks to be part 2 of 3 of a set of CBS color techs info from 1951. Describes the CBS Color Companion along with a TeleTone Color Companion. That one is new to me.

I'm aware of volumes 1 & 2 of the Color Notebooks. Is there is a 3rd volume?

I do not think there was a 3rd volume. Volume II is dated September 1951, and (as you probably know) the CBS system was Kaput by November. Pity.
