What's wrong if your bed room is red...?

Okay so my room is basically red, the curtains,mirror,my bedspread, my study table,chair,lamps,my cell phone,my laptop and my camera. I am actually obsessed with the colour red actually shouldn't say obsessed I like the colour red but it is not my favorite colour purple is . Someone told me that the color red might affect my brains, bring a change in my personality and that it is not good for my health. Is it actually going to affect my health?? Because the person who told me isn't even physiologist she is just a teacher. And I also understand that the colour red stands for the emotion “angry”, but being short tempered is like in my genes. Depending on the situation sometimes I do get angry but I know how to control it anyways I really don’t believe in these superstitious things, the only thing that I want to know if this myth is actually true??
