Feng shui is the method, the art of design and natural positioning of the universe. A peaceful life must achieve balance and harmony between the yin and yang. A design, a perfect picture must apply the law of yin and yang. Thus, color is also classified as yin and yang and it is also used in the theory of five elements. 

The hot colors like Red - Orange - Yellow are Ocean (In the primary color circle it is colors from 01 to 48) 
The cool colors like Blue - Green are Amber (From colors 49 to 96 on ring basic color circle) 

Kim = represents white. 

Jupiter = Green. 

Water = Black. 

Fire = Red. 

Earth = Yellow.

Any action in the Five Elements is correlated with other actions in the relationship of mutual or mutual.

Actions that can be combined and co-ordinated are: 
Water and Carp = Black and Green. 
Jupiter and Fire = Green and Red. 
Fire and Earth = Red and Yellow. 
Turkey and Kim = Yellow and White. 
Kim and Shui = White and Black. 

The incompatible and unmatched actions are: 
Earth and Water = Yellow and Black. 
Water and Fire = Black and Red. 
Fire and Kim = Red and White. 
Kim and Mộc = White and Green. 
Jupiter and Earth = Green and Yellow. 

Similarly, when mixing colors from two or more colors, the same principle applies. 

Example: 
Coordinate three actions to have the following: 
Kim - Thuy - Moc = White - Black - Green. 
Carpentry - Earth = Green - Red - Yellow.
Earth - Kim - Water = Gold - White - Black ...
