I have one question on the color for the main gate and main wooden door. My main door is facing south. I read thru some note that it is important  to paint the door according to facing direction to enhance flow of chi into the house. However, south is a bad direction for kua no 7(male), by painting the door according to south direction, will it encourage flow of negative chi to our house? As south is a bad direction for both Me and fiance.

Thanks a lot.. Hope to get it reply. Tks.

Yes, colours are considered for the main door. If your door is made of wood and color in wood range like  maple, pine, teak it always alright as this is considered neutral.

If you want to use bold colours like red, blue and green then plot out the Flying Star chart and check whether that sector is suitable or not.  For example, if the sector has a Water Star #8; then best not to paint the main door red. Actually one should never use red except you stay at a temple.

Cheers.
