Incidentally, while I was at Lotus of Austin today I noticed a couple of brightly colored cars. . . One was an Elise in Krypton Green, and the other was an Exige in Laser Blue.
Krypton Green has been an unpopular color, and has been called names like "Chernobyl Green" or "Grasshopper Green". I think Lotus have dropped it from the 2008 catalog (along with Aubergine Purple, darn it!). It really looks bad in photos. Today was the first time I've seen one "in person", and I thought it looked fabulous. Some things you just can't capture with pixels.
The Laser Blue Exige was also quite impressive. It's not a super-saturated blue, but when the sun hits it. . . ahh, the sparkle! Definitely a paint that likes the sun. That's something else hard to capture in photos.
I understand Lotus are introducing some new paint options above and beyond the old Solid/Metallic/Lifestyle options. They are going to offer a prismatic paint that appears different colors when viewed from various angles. Somebody on the Lotus forums posted this photo:

I believe that's a custom paint job, not the actual paint Lotus will be using, but it gives you some idea of the visual effect they are going for.
