Tbh, I haven't still understood fully what is the exact issue? however, it seems that color on outside is black, and below black, it is white color which is worrying and bothering you.
Brother if it has been bought via auction, do you have its auction sheet?
Color code is mentioned in the auction sheet. From Color Code, one can get idea about the original color of the car.
(When I self-imported my RED Vitz last year from Japan, the color code mentioned on my Auction Sheet was "3P0" which translates to "Super RED". So, in my case, there isn't any conflict)
