If you clothe someone in orange. Specifically a fluorescent hi-vis orange. Something strange happens.
There’s a secret power that creates a stillness in them. They stand. Sometimes they lean. But always still, like an evil voodoo has robbed them of motion. Often they get trapped in this stupefying state in groups. Threes, fours and more, frozen together. Sometimes they bend down. Sometimes they hold something, such as a sign, or a cigarette, or a clipboard or a tool. Sometimes they gaze collectively at a large piece of paper one holds. The spell only seems to impact on their ability to walk, as speech seems unimpaired.
Orange is my favourite colour, so this secret power it seems to possess, freaks me out a little.
