Colour picking and another redesign!

The typeface I was using was causing some concern to some students, as it is a web font. Therefore I have changed the font to DIN which is a really nice one. I know that I want to use a colour on my business cards and throughout my branding. I think a whole colour on the home page of my website and also a block of colour as my image on twitter rather than my logo. These block colour tend to work nicely to tie a brand together. I am thinking a nice pastel blue like the azure blue GFSmith paper I found.
