Watching Iowa St. vs. Oklahoma

[tonatiuh]

I'm watching the game between Oklahoma vs. Iowa St. in Ames, Iowa. It appears as though the Iowa St. team has changed colors at least for this game.
All the fans are wearing the Cyclones usual red & yellow colors, but the the logo on the field and end zones along with the team uniforms is black & gray
similar to Raider colors.

Have they changed their colors recently, or is this just colors they are wearing for this game?

The Clones are still red and gold. They break out the all black unis every now and then.
