I moved in to my new house in February this year. Since then, my younger son has fall sick twice. The color tone of my new house is yellow and peach. One of my relative told me that yellow is an unlucky color this year and it will bring a lot of sickness. Is this true? If true, any countermeasure? Kindly advise. Thank you.

From the balcony of my house, two smoke duct perhaps from a factory can be seen from far. This looks like the joss-stick that Chinese used for praying. I read from a book that this is not good for Fengshui. Please advise on the method to counter-act. Thank you.
