Important Vastuchakras
In cases where alterations in a Vastu are difficult to execute, remedies on Vastudoshas can be found in the various Chakras (schematics, charts, or tables) recommended by the Vastushastra. The chakras commonly used as reference are Avakahada Chakra, Shri Ranga Chakra, Parinit Chakra, and Dwar Nivesh Phal, along with the all encompassing Vastu Purush Mandal.

Shri Ranga Chakra and Colour Scheme for Painting
Every person has his preferences regarding various colours of nature. Colours can be pleasant or irritating depending on the personality involved. But, the underlying principle of Shri Ranga Chakra is the correlational pattern that can be defined between a colour shade and the virtuous qualities of the panch-maha-bhutas , agni (fire ), prithvi ( earth), vayu (air), jal (water), and akash (ether). In Jyotishshastra, the twelve astrological signs are assumed to have close affinity to a particular tatva (principle) of the five basic elements. The friendly or hostile relationship between various signs of zodiac and principal colours is indicated in Table.
