The conference title was "Thinking Beyond: Transversal Transfeminisms"
Delegates attending the one-day forum at Roehampton University, south west London, were invited to wear different coloured lanyards to ensure they did not feel emotionally overwhelmed by sharing ideas.
Those wearing red badges did not wish to engage with their fellow academics, while those in yellow did not want to be approached and would only communicate if they made the first move.
Green badges were worn by attendees open to conversations.
Academics could change the colour of their lanyard depending on how resilient they felt at different points of the conference.

The original report was in the Times but because of paywall I have used this link. Think the Times had more detailed.
I am more upset by the idea that anyone should think this has anything to do with feminism.
