Popular cereal company Kellogg's was put under fire for racially insensitive cartoon on Corn Pop cereal boxes Tuesday.

The racist cereal box was called out by Marvel comic writer, Saladin Ahmed, who noticed the lone "brown corn pop" was depicted as a janitor.

Ahmed took to Twitter to express his discomfort with the cartoon and said though a "small thing", he did not want children to become accustomed to racism.

"Hey @ KelloggsUS why is literally the only brown corn pop on the whole cereal box the janitor?" Ahmed tweeted. "This is teaching kids racism."

"Yes it's a tiny thing, but when you see your kid staring at this over breakfast and realize millions of other kids are doing the same," he added.

Kellogg's responded to Ahmed complaints around five hours later, saying the cartoon was not created with the intent to offend. However, the cereal company will update the cartoon.

"Kellogg is committed to diversity & inclusion. We did not intend to offend – we apologize," the company tweeted. "The artwork is updated & will be in stores soon."

Ahmed responded with gratitude for the company's swiftness to respond and act on the problem and later added the amazement of the impact he was able to have.

"Today I used the computer in my pocket to get a cereal company to make their boxes less racist," Ahmed tweeted. "What even is the 21st century."

Kellogg's is not the first company to be scrutinized on Twitter for racist advertisements. Skincare companies such as Dove and Nivea were also blasted on social media for their depiction of skin-lightning.

William Adoasi, CEO of Vitae London, called out Nivea on Twitter Oct. 18.

"This is why black businesses need to rise and cater for our needs," Adoasi tweeted. "Nivea can't get away with pushing this skin lightening agenda across Africa. Appalling."
