Colour scheme

Just like I am a black-and-white person my apartment is equally black-and-white. I believe that either a person is good or bad, that you tell the truth or not, that there are no grey areas. Which means my flat is reflecting the same. However, one of my dear neighbours who visited last Friday was commenting: "it is very black and white" and I think he's right. It is time to factor in some colours. I'm thinking purple, pink-like purple, blue-like purple. But only on cushions, placemats and peripherals. After all, it is my flat and it should reflect me. Not anybody else. And I already have a multi-colour lamp. I can choose to have the red-light-district, the green lamp (signalling exactly what?) and the blue colour. So colour it is. I have to go shopping. Arrrrgggh!
