Extension cord color is about visibility, not quality.

No. Yellow or orange jackets don’t mean the cord is any better—they just make it easier to see on a job site or in the dark.

Most heavy-duty extension cords (the ones with 12 or 10 gauge wire, thick insulation, and a “S” or “W” rating) come in bright colors because people trip over black cords. On a construction site or in a garage, you want to see where the cord runs so you don’t yank it or run it over. That’s really all the color is for.

The actual quality comes from the gauge (lower number = thicker wire = less voltage drop), the insulation type (look for “SJTW” or “STW” on the jacket), and whether it’s rated for outdoor use. A black cord with those same specs is just as good. A cheap orange cord from the hardware store with 16-gauge wire is still a cheap cord, just easier to lose in the grass.

So color is a feature, not a badge of honor. Buy based on the wire specs, not the jacket color.
