Meaning of wearing red to a wedding

I think it's a made-up story by the site "buzzbait" as click bait.

I remember thinking that was a "rule" when I was younger - you don't wear white, black or red to a wedding. And you don't wear red (or any bright colors) to a funeral.

Now, I think you pretty much don't wear white to a wedding. Everyone wears red and definitely wears black.

The only time I've heard about not wearing red is to a traditional Chinese ceremony because the bride usually wears red. But, other than that, I've never heard about not wearing red to a wedding.

My mooto (ex-husband) always wore a red tie to a wedding. Men usually wear white ties. He believe red symbolized the colour of love.

China, white is what you wear to a funeral.

OMG It really annoys me that someone has made up all of these ridiculous meanings to colors. The only one you shouldn’t wear is white. Everything else should be totally fine. If you look up all of the dumb things people have made up, there literally are no colors left to wear. If someone told me I couldn’t be at their wedding because of the color I chose, we would no longer be friends.

In that vein, both my mom and my grandma wore warm white to to my wedding. (Like, not even cream, it was just barely off white.) They were clearly not in bridal gear, though. I was in a very traditional style ballgown. My mom was a little bigger, and tried and tried to find a dress that she liked and felt good in. I was with her when we found a gorgeous knee length cocktail dress that she felt great in, but I could tell she wasn't going to get it because of the color. I told her that I didn't care what the hell color she wore, I wanted her to feel good. And you know what, she looked gorgeous! My grandma had a very chic knee length cocktail suit that she wore in keeping with our unofficial theme. All 3 of us looked damn good, if I may say so! And no one mistook them for the bride for even half a second.

My ex-MIL wore red to our wedding. She was close with her son, my ex-husband, but not THAT close
But I have heard about the no red to weddings before. I live in Norway, maybe it's an old wives tale from here. Not sure.

My Grandma was horrified when I had red roses as my wedding bouquet and red accents for the bridesmaids dresses etc because together with white (cream) to her it signified blood and bandages.

Needless to say (to those in the know) my dearest SIL wore a cream dress and a huge red hat and red high heels 

I wore a burgundy dress when we got married, and when I was my bestie's MOH this past September, I wore burgundy again. She said she'd be fine with me wearing my wedding dress as my MOH dress, but some of the lining is a little past where the end of that dress is now, so I got a new one.

Sounds like her whole outfit needed to be addressed.

(no disrespect to your cousin I’m sure she’s a nice lady)
