If you’ve ever stared at a tube map and thought, “Wait, is it purple or pink?”—you’re not alone. The Metropolitan Line has a notorious battle with the District Line, which wears a very similar, slightly greener green. But its real nemesis is the Hammersmith & City Line, which was given its own pinkish-salmon colour in 1990. Before that, it was all one big, confusing purple family.
Here’s a fun, awkward fact: The Metropolitan Line’s colour was originally a dark crimson, closer to dried blood than the vibrant jewel tone we know today. It wasn’t until the mid-20th century that TfL’s designers standardized the map and settled on that distinctive, moody purple. Purple is the colour of royalty, after all, and this line once carried the Victorian elite from Baker Street out to the leafy suburbs of Middlesex.
Where the Colour Lives: A Practical Guide
You can see the real colour at its most honest if you take a trip to Aldgate station. The station’s roundels still use an older, slightly faded version of the purple, like a vintage Polaroid. For the purest experience, grab a seat on a westbound train just after sunset. The station lighting at Uxbridge casts the purple signs in a deep, almost cobalt glow.
Need a cultural touchstone? Think of the colour as Prince’s wardrobe on a rainy day—purple, but with a practical, commuter-friendly edge. Or consider it the shade of a perfectly bruise-ripe fig you’d buy at a market near Pinner. It’s a colour that works nine-to-five and still knows how to dress for dinner.
