There is a new challenge blog that is about to start up. You have to use the colour black as the main colour and then they give you two other colours to team it with and a sketch to interpret. Recently they had a Design Team Challenge and I gave it a go. I didn't make the team (just as well as I am a bit busy at the moment) but here are the layouts that I did for it. This is the link if you would like to see more; http://www.blackmagicsketches.blogspot.com/
I must admit I had a lot of fun doing these pages and I think that a album full of mainly black pages would look stunning.
