Help with exterior color!
 

Hey guys, I'm currently in the process of getting my first Audi. It's going to be a '17 S5, the main issue I'm having is with the exterior color.

After much debate, I've settled on Estoril Blue Crystal. However, it seems that the color isn't consistent: sometimes it looks almost sparkly, sometimes it looks flatter, and sometimes it just looks plain dull. At first I attributed it to lighting, and maybe wear & tear...but then I was kind of shocked to discover that there's actually three versions of EBC: EBC, EBC Crystal Effect, and EBC Metallic.

Now I'm just thrown for a loop and do not know what the difference is...
