I'm thinking a paint sceam something similar to Dan Goodmans car or the one 4cruizn posted in the bodyshop under grill ideals. The car is viper yellow now so maybe that on the bottom with plum crazy on the top??? Still thinking.
I personally am not too crazy about any two-tone Cuda, except the way Chrysler offered them with a painted roof. I love those, but you rarely see one. Purple and yellow Cuda
. If it has to be two-tone, you might want to consider silver/gray, black/gray, white/silver or something to that extent. Two bright colors together rarely looks good in my opinion. A more subtle two-tone looks more clean/classy and bright colors usually look, well, a little gaudy. Very nice looking car, keep us posted and good luck.
