this is a bit embarrassing - but I swear that it wasn't blue yesterday! I had the two browser windows open side by side and the BBC one was black.
I don't use software, I write all my pages up in HTML myself. That's why, when I see a page I like I tend to want to look at the source to see how they did it. I quite liked the colour scheme on the BBC page and wanted to see what palette they used.
Meanwhile - does anyone know if it is possible to change the colour of the drop down arrow?!
