Kitchen in North West is fine.
Cooking person in the Kitchen should be facing either the East or the North Direction.
If the cooking slab is in the East to West Direction, the Sink should be on the East end of the slab and the cooking oven should be in the middle or the west end of the slab.
Shelf to keep utensils should be in the west end of the cooking slab.
Shelf to keep cookware, groceries etc, it should be on the back side of the cooking person/South wall of the Kitchen.
Ideal colour of kitchen shelf is white and the second option is cream and light yellow. These colour helps the people in digestive system. They improve in mental work. The red, black and blue colour are always avoidable.
