I think the choice button should be left at the bottom so each member can use the colour that suits
What is the 3rd site, I know Wildcamping and Motorhomer but I don't know the third?The more I use the blue, the more I love it and it makes it a breeze to know which site you're using. I'm still feeling loyal to the idea of all 3 sister sites having similar 'branding' but it's definitely blue for me now. Maybe just having the same sort of layout and style is enough of a nod to site 'sisterhood'. I'd be gutted if the blue disappeared now!
