And a suspiciously clean white hard hat.

  In my experience, common yellow/white hard hats are what workers wear. Management tends to wear rarer colors, like green/blue/red.

    There's a defacto code here (UK), yellow is labour, blue is trades. white is engineers, grey is visitors. green is safety (H&S/medical), pink is the noob who forgot his hardhat.
