Harmonizing colors

I started a little experiment after attending Joey Yap’s Thrive workshop.

Using the elements of controlling for eg:

Earth(brown/yellow) controls water (black/blue)

Wood(green) produces fire(red) which nourishes earth.

My self element is Earth. Therefore i had always avoided colors like blue, black n green. However, when i use brown with blue or black, i feel more stable and not emotional.
