Julian,
here is a picture of an original paint Bahama Yellow on a Elan Plus 2. It was my car until I (like an idiot) sold it to a fellow in Vancouver Canada.
It took a while for me to warm up to the color, now I like it.
Many manufactures used similar colors under a different name, such as Porsche, British Leyland (MG, Triumph etc.), Chrysler, Fiat and Aston Martin.
But I found the Lotus pick to be a little richer in hue. That was one of the reasons I considered bidding on your car......the original color.
