The Red Cross is apologising after a poster depicting pool safety rules was circulated on Twitter and flamed for being “super racist.”

The poster, which shows a crowd of cartoon children committing an array of poolside do’s and don’t’s, was spotted at the Salida Pool and Recreation Department in Salida, Colorado.

A Twitter user put a picture of the poster online, where people debated whether it was, in fact, offensive or not.

“Be Cool, Follow the Rules,” the poster in question advises.

Below that, a number of children are swimming in the pool or at the edge of the pool.

Arrows point to certain children, indicating “not cool” behavior with a red arrow and “cool” behavior with a green arrow.

It just so happens that the two children exhibiting “cool” behavior are white. A blonde girl in a blue bathing suit smiles as she is about to step onto the diving board.

The majority of the kids being “not cool” are children of color. One is pushing another child into the water, another is running and a third seemingly diving into the pool.

Those who found the poster questionable took issue with the fact that children of color were doing dangerous activities, while all of the acceptable, “cool” activities were depicted with lighter-skinned people.

“Seriously, @RedCross? Behaving white kids are ‘cool’; children of color depicted as misbehaving/‘not cool’ #racism” wrote one critic.

Another woman tweeted at the Red Cross, saying the poster was an example of institutional racism.

And one man didn’t understand what the fuss was all about:

Though there were those that thought the interpretation was a bit of an overreach, the Red Cross swiftly apologised, replying to the original tweet and later issuing a statement.

“We deeply apologise for any misunderstanding, as it was absolutely not our intent to offend anyone. As one of the nation’s oldest and largest humanitarian organisations, we are committed to diversity and inclusion in all that we do, every day,” it wrote on its website.

The organisation also said it has removed the image from its website and app, and has requested the poster be removed from aquatic facilities. The Salida Rec Center also tweeted that it had removed the poster and “didn’t scrutinise it like we should have.”

The poster was originally part of the Red Cross’ 2014 “Aquatics Centennial Campaign.”

“We are focusing on areas with higher-than-average drowning rates and participants who otherwise wouldn’t have the opportunity to take swim lessons,” the Red Cross wrote.
