You might be wondering why there are so many different coloured hard hats in the pictures of the LBA build. I know I was when I saw the first pictures on Monday. Turns out the colours are used to indicate the role of the person wearing the hat. And here's the key:
Light Blue = Team leader (or 'Lieutenant')
Dark Blue = Team member (Oxford)
Red = Team member (Soton/Ports)
Yellow stripe (on any colour) = Coordinator / Quality Assurance
White = Media or Visitor
White with green/blue cross = First Aid
We won't be able to keep up with labelling all the different people in the pictures this week, but hopefully this key will give you some idea of who you're seeing.
