Bathroom in center house

Dear Mr. Lee,

I wanted to thank you for answering some of my other questions. You've been a great help. My other dilema is the bathroom located in the center of my house on the first floor. I have read on many websites that I should put a full length mirror on the outside bathroom door, which I plan to do. But I'm a bit confused with the colors. Many websites say neverput anything red in bathrooms because it's too yang. But then I found others say if the bathroom is in the center of the house, I should paint the walls red, orplace red rugs around the toilet, andplace stones, crystals, and green bamboo plants. Right now my bathroom is just plain black and white. I have whites walls, white rugs, black and white paintings of skyscrapers, chrome fixtures, and a chrome shelf over the toilet. Can you please clarify and suggest what I should do? Thanks for your time again!
