One thing I have learned in the world of Flowers and Interior Design...always follow the fashion trend in clothes and you'll never go wrong.

Whether we like it or not, the gurus of the fashion world really do dictate well in advance what colours are in and what colours are not. So when you're looking for inspiration theses colours can sometimes be a good starting point.

A lot of the public can unwittingly follow trends, choices in colours they decorate their homes with are no different.  So if you're creating crafts for the home you will want them to blend in.  Subconsciously people will also be drawn to colours they associate with at the time or that they see a lot of, or even because they're wearing those colours right now - if they're wearing them then they must like them.
