Can I ask you what you base your color theory on? Is there something on the internet that I can read to learn more about how you are interpreting the use of color? I have read a very, very little about color, mostly the "yellow makes people angry" "red is stimulating to the digestive system" variety, but nothing that really delves into color choices as a representative of psychological predispositions.
I personally find most people decorate their homes with colors that are popular at the time they apply the paint, buy the comforter, etc. So while color theory may count for something, I think we'd need to know WHEN the house was decorated and if the colors chosen were the "usual" for that time, or if it was decorated with colors deliberately off the beaten path. I know if you look in my house, you will find no avocado color, simply because I don't like that color AND
it ceased being popular in the early, early 70's.
I regret to inform you that it is actually popular again. Sorry.
I think we may see a lot of tasteless eclectic when multiple families are living in the same home.
PG and NG surely lived somewhere before moving in with mom, and I would assume that some of the mis-match comes from them bringing their possessions with them when they moved in. (I say this because an adult son moved back home for a short while, and I had "his" furniture and decorations dispersed through-out "my stuff" while he was here. Talk about tasteless eclectic!)
