Violets are blue

Despite the fact that my interior design company is called Blue Mahogany, blue is actually one of my least favourite colours. Just thinking about it, the only time I have ever come up with a blue scheme, it was pretty much unavoidable as the clients' corporate colours were blue and white. The closest I have ever done without prompting is duck egg I believe, and that was only as an accent colour.
Seeing as I am a strong believer that although the interior designer's style will come through to some degree, interior design is really not about what my personal preferences are. So I've set myself a challenge: Design a blue room. I mean, really blue (whatever that is...). To be really strict, I've decided that turquoise doesn't count either! Oh my... let's see how this goes.
