Hi, I have both the Diamond Feng Shui course and the Diamond Quantum Colors course. From my experience with both courses, you will need to get the Diamond Feng Shui course first so that what you learn in the Quantum Color course makes since. I think if I had the Diamond Quantum Color course first I wouldn't have understood it at all. It all made since because I had studied the basics of level 1 Diamond Feng Shui plus Level 2 and Level 3. So by the time I got to The Diamond Quantum Color course it all fell into place. It would be like putting the roof of the house on first before you built the stable foundation. And foundation is the key to learning.
Best wishes for the future
