Greetings, i've noticed that my Rubik's cube has wrong colors.

Instead of having 6 pieces of different colors x9 (9White,9yellow,9red,9green,9blue,9orange), it has 5 pieces with the white ones replaced by blue ones (9yellow,9red,9green,9orange,18blue) and not only that but the opposite sides are different from what it originally is. For example, the opposite side of yellow is blue, the opposite side of orange is blue again and the opposite side of green is red. Is it solvable or not? A great uncle of mine has solved it, he says!
