Why did they miss the most important Technicolor, 3 color Technicolor?

The book is about 2 color Technicolor only.

Maybe it wasn’t important to them at the time, not many people had a tv to watch it back then, only movie theater could show it

They made a book about Technicolor but the book only mentions of 2 color Technicolor.
