The Commodore 64 was produced for a 12 years from 1982 to 1994. It had several iterations of case color, keyboard color & keyboard labels, badge etc.
Commodore was famous for using whatever parts they had in their stock. You can find different combinations like dark brown bread bin case with dark colored key caps and silver badge or vice versa. Electronics inside also had several variations that I don't want to mention here.
When it comes to the case color, I knew four variations: the original design a.k.a. bread bin had two variations. The original was dark brown and later editions were light brown. Then came the wedge design with lighter beige or white coffee color. Finally there was C64G which was manufactured with a bread bin case made in the same white coffee color as the wedge case.
However today I happened to see a picture that confuses me.
I know the plastic became more and more yellowish with time. So the yellow cases at the top row and second row from the bottom are ok.
What intrigued me, the gray cases at the bottom row. I didn't know the Commodore made a case in this color. Did Commodore ever produced gray colored Commodore 64? Are they real or just a false color due to exposure or white balance settings of the photo?
