Blue Ethernet cables don’t perform any differently to other cables; the main reason for colored cables is to aid identifying and organizing network connections.
If you’re even moderately familiar with computers and networking, you’ve probably fiddled around with a cable that connects your PC or laptop to the Wi-Fi router. This is what allows you to use wired internet on your device, through technology known as Ethernet. While Wi-Fi is great, switching to a wired connection is one of the most effective ways to speed up your computer’s internet speed — especially if your Wi-Fi is spotty.
If you’re dealing with a typical desktop setup, you’ll realize that most of the cables and connectors are painted black — perhaps except one. Blue is a common colorway for Ethernet cables, and you may have wondered what it means. The short answer is that it doesn’t really mean anything. An Ethernet cable’s color is just that: a color. So, whether you’re looking at a jet black Ethernet cable designed for gaming or a blue one, know that its color has nothing to do with performance.
That said, colored Ethernet cables do serve a purpose — that of organization. In complex setups with multiple devices, color-coded Ethernet cables make it easier to tell which connection goes where.
