This is a portrayal of internal system color coded hierarchy with associated imagery.
Purple is highest and represents the most power and high spiritual plane.
Blue is a kind of everyday gateway system who tends to be spiritually oriented as well. The branching represents how purple came from the blue section somehow.
Green is the structural and technical area. It holds mind control experimentation and the more
sophisticated programming is based here.
Red represents sexuality and slavery. The curtain indicates performance and being used by others.
