Many original PlayStation game discs have a distinctive dark underside, but the evidence does not establish that Sony chose the color as copy protection. Sony did use copy-protection information on production discs; that is a separate, documented feature. Sony’s published histories explain why PlayStation used CD-ROM, but do not give a definitive reason for the discs’ dark appearance.
What looks black on a PS1 game disc?
The dark color is visible on the underside of many original PlayStation game CDs. The collected sources do not establish that every licensed disc, regional release, or reprint has the same appearance, so color alone cannot confirm whether a disc is genuine.

Was the black underside copy protection?
That explanation is often repeated, but the available evidence does not verify it. A USPTO-hosted technical exhibit describes PlayStation discs as CD-ROM XA and says Sony added copy-protection information to production discs. It does not say the dark color carried out that protection or explain why the underside looked dark. The technical exhibit
In other words, a disc could have encoded copy-protection information and a distinctive physical appearance without the color itself being the security measure. The precise reason Sony selected the dark coloration is not established in the sources cited here.

Why did Sony use CD-ROM for PlayStation games?
Sony’s official history says PlayStation games used CD-ROM, which offered more room than cartridge alternatives. Sony also describes practical production and distribution advantages: its corporate history says an order could be fulfilled in a maximum of six days, even in small lots, whereas restocking cartridges took several months. That is Sony’s stated business rationale for the CD-ROM format, not an explanation of the discs’ color. Sony Group corporate history
PlayStation’s official history likewise says CD-ROM let games be much bigger than cartridge alternatives and enabled titles such as Final Fantasy VII to be manufactured faster and more affordably for players. PlayStation history timeline

Can disc color prove a PS1 game is authentic?
No. The available evidence does not show that all genuine PS1 discs share one underside color, or that color is a reliable authenticity test. Assess a disc through its full condition and identifying details rather than treating a dark underside as proof of authenticity or protection.
