DrDamn I wasn’t suggesting negotiating with the brand, besides which as far as I know EG don’t even decide which ad goes in there, they just rent the space to an ad broker. It just makes ads (to me anyway) even more jarring if you get a predominantly red advert on a website that is predominantly blue say. In design terms, keep it to the colour wheel guys 🙂.
Mind you, the brands may like it because it makes their ads ‘stand out more’.
