I chose the colour blue. It's one of my favourite colours and has always had a calming effect on me. After doing a little bit of research I found that the colour blue has many more connotations.

1. Stable and calming - can make time pass more quickly and help you sleep
2. Too much blue can dampen spirits (the blues) or cause sadness or depression
3. Brings peace or keeps bad spirits away in some cultures
4. Corporate when navy/dark - conservative business power suits and police uniforms
5. Royal blue/azure can show wealth
6. Slows human metabolism and suppresses appetite
7. Trusting and loyal
8. Confidence and intelligence
