Lets see, Ibanez marketers are sitting around in the Autumn months, thinking what color for a left hand bass would sell best in North America, and one of them realizes it's getting close to Halloween in the US. What are the favorite colors of Halloween? Black and Orange. Kids love Oranges, and the little candy-corns, that are Orange and White, so, what if we go with Orange for the US? Agreed they say.
Now, what about Europe, someone asks. What is one of the most prominent features of Europe, someone says. After tossing around different color features. Blue Danube, Red Sea (OK, this guy doesn't really know his geography), etc., someone says, what about the Black Forests of Europe. That's been a part of the peoples of Europe for thousands of generations. Alright!, they say, it's settled. Amber-Orange for the pumpkin eaters of the US, and North America, and Trans-Black for the countries of Europe. See that wasn't so hard. Get a note off to production!
