Thanks for the feedback.  I agree the colours were bold, but, Mr G and Moray, I'm surprised you say they clashed as red and blue are supposed to be complimentary colours.  Bold = good.  Clash = bad.  I've toned them down a bit by introducing some grey.  The difference isn't massive but I think it's enough to take the brashness out.  What do you reckon?
Thanks Speed - I'll try the greens, but I'm quite keen to stick with the blue and red because I have plans to continue the colour scheme elsewhere.  
Moray, don't touch Yellsites with a bargepole.  I experienced rubbishness beyond description, and probable internal corruption.
In case anyone's wondering, I'm call myself camvan because I intend to relocate to Cambridge soon.
