USCF Rules Regarding Promotion to a Piece of the Opposite Color

I was at an OTB tournament today and accidentally tried to promote my pawn to a queen of the opposite color by accident, twice (I know). I wanted to promote my pawn and reached for the nearest queen, which was of the opposite color. The second time, I actually placed the queen down. A few seconds later I changed the queen to my color. This got me wondering what the USCF rules say about opposite color promotion. I remember several years ago I saw a post (or something like that) with a puzzle where mate in 1 is promoting to a black knight as white. It says that FIDE changed the rules, but I was wondering what USCF says on rule. Could my opponent claim that I promoted to a queen of the opposite color and play on or would that be considered an illegal move on my part? (Also, does anyone know the rules regarding illegal moves in USCF classical games?)

I don't know how I tried to promote to a queen of the opposite color twice in one day. I'm probably used to sets with double queens.

"3.7.5.1
When a player, having the move, plays a pawn to the rank furthest from its starting position, he must exchange that pawn as part of the same move for a new queen, rook, bishop or knight of the same colour on the intended square of arrival. This is called the square of ‘promotion’."

Do you know what uscf says on the topic?

FIDE > USCF

FIDE has no bearing if the game is played only under US Chess regulations.

@GoldenDegree, if I remember, and no one else answers, I'll look at the rulebook this evening, but I think it specifically says it has to be of the appropriate color, so anything else would be illegal 

I’ve seen this situation happen and it was hilarious. White accidentally promoted a white pawn to a black queen, and black then tried to move this queen and use it as their own piece. 

Promoting a pawn to the opposite color? Looks like the pawn becomes a traitor after getting education and wealth in the opposite kingdom so he changes his mind

USCF Rule 8F6:

Lol. My opponent did look disappointed when I corrected my mistake but didn't challenge. I was playing a kid who also tried to make me move my king when I accidentally knocked it down which got me thinking.

Thanks, @blueemu

”Oranges are better.”

@goldendegree you have to use the piece of the same color, obviously, but I’m not sure on any punishments for accidentally using the wrong color. Seems like a very unlikely scenario tbh lol

I tried to promote to a queen of the opposite color twice in two games on the same day though. I wonder if touch-move applies to pawn promotion.

"Is theft forbidden in Kentucky?"
"Theft is a fellony in the whole USA."
"I was asking about Kentucky."

I was saying that the OP asked about USCF rules and got some “fide is better than uscf” response which was unnecessary.

Wrong analogy. 

Your reply was more like :

"Is theft forbidden in Kentucky?"

"Theft is a felony in the whole EU."

FIDE applies worldwide...

No, it doesn't. 

Rated events in the US are run under US Chess regulations, which has differences to FIDE. That is the case unless the event is also FIDE rated or the TD/Organizer just wants to use FIDE regulations and advertises it in pre-event publicity.

It's even possible for events to have other, non-standard rules, if advertised in pre-event publicity 

"A necessary condition for a game to be rated by FIDE is that it shall be played according to the FIDE Laws of Chess. It is recommended that competitive games not rated by FIDE be played according to the FIDE Laws of Chess."

That does not contradict anything I said.  Recommendations are just that, recommendations. Some US Chess regulations are different than FIDE.

Most events in the US are not FIDE rated and that won't likely ever change
