What’s black and red and hot all over?

There are clear signs that Black Widow, the new Marvel superhero film starring a redheaded Scarlett Johansson, has infiltrated the culture. “According to the website Justmylook, there has been a 163% spike in demand for the colour since the release of Black Widow,” wrote AIR MAIL’s own Stuart Heritage in The Guardian, “presumably because lots of people sat through two hours and 14 minutes of a film about a woman grappling with the psychological torment of knowing she was part of a Soviet military programme that brainwashed, sterilised and murdered hundreds of abandoned girls, only to think: ‘Ooh, I bet I’d look lovely with her hair.’”

But everyone should tread carefully. Jeeves, as you surely recall, considered the color “dangerous,” and more than once had to warn Bertie Wooster away from getting involved with anyone—usually the alluring Bobbie Wickham—“with quite such a vivid shade of red hair.”
