The answer, surprisingly, is yes. Blue Christmas lights are Jewish, but they’re also Catholic and Muslim.

Blue Christmas lights are actually called blue-white, which means they emit a combination of blue and white light. They’re used in Christmas decorations because they have a festive feel without being too obvious about it.

Because blue-white lights are so common in holiday decorating, you might think there’s nothing special about them at all. But that’s not exactly true. In fact, the history of these lights dates back to the 1970s when a British company called Sainsbury’s decided it wanted to sell more energy-efficient products for its customers.

According to Sainsbury’s website, this led them to create a new type of string light that would use less energy than traditional incandescent bulbs:

“In 1978 we brought out our first ever range of energy efficient light strings (now known as Blue White) which were very popular with customers who bought them as gifts.”
