While digging through the documents, that were provided recently, by Antony Beckett on facebook, I found the power supply description.
Under the chapter:
3.2 color (Enclosure and cables) is written : Commodore Basic Light Beige (MunsellBitte melde dich an, um diesen Link zu sehen..0Y 7.58/1.4; Gloss 10+2 on 60 deg. gloss meter).
Does anybody know, if this is a valid colorcode? Or isn't this a colorcode at all and maybe a plastic grain mixture?
Does the C65 and the C64c have the same case color?
