The most baffling part though - and I hope someone else can shed light on this - is the banner ad at the top. When I wanted to check how the site displayed in another browser, I was surprised to find that then that banner is adblocked, suddenly it becomes a whole world of navigation previously unseen. I don't understand.
Anyway, the colour problem was mainly why I wanted to bring it up. I was going to contact them to make the suggestion that they should change to a friendlier colour scheme, but none of their contact email addresses are suitable. Probably on purpose.
