I am pretty sure that is House of Kolor color.
Might look over their site:

I am not sure of the name of the color but have seen it in person , and its diffinately bright!

Lamborghini has a real bright Yellow Pearl & Pearl Orange that really POPS. Go to an automotive paint store and look at the chip books in 2000-2004 Lamborgini, and see what you think of those. They may even have a House of Kolor chip book you can look at also.
