Cassis

Cassis is an Audi Exclusive paint color with a pearl effect finish. It's a dark purple which takes on lighter purple (almost pink) tones in brighter lighting. Due to the pearlescent nature of the paint it changes color depending on lighting and angle you view it and reveals a subtle burgundy undertone in certain conditions.

Due to it only being offered as a special request Audi Exclusive option, it's quite rare to come across.
