Blue because it is calming.
That was what I was going to say :)
Purple, Pink and Cyan (: Because they are pretty to look at.
Black at the moment, doing home decor - black being the main colour including some walls. The people who said - you can't do that! Are stunned at the result - it is stunning.
Green its just so natural
Burgundy cause it's Burgundy and I like it
black because it contains all other colours
