Sharing an image of the elaborate creation on Twitter that has received nearly 30,000 likes, Kohli, who was also a former contestant on "The Great American Baking Show", celebrated what makes him unique, reports The Huffington Post.
"I'm proud to be a bisexual bearded baking brain scientist," he captioned the image. "I feel fortunate to be able to express all these aspects of my identity and will continue to work towards ensuring the same freedom for others."
Pride Month kicked off on June 1 and honours the LGBTQ community while commemorating New York's Stonewall riots in June 1969 that signalled a turning point in the movement for equal rights.
In an interview to Buzzfeed News, Kohli said: "A few years ago I saw a photo of another Sikh man at a pride parade who had a few colours in his turban.
"I was looking at that and I realized the way I tie mine, it had the exact right number of layers to make a rainbow."
He wore his rainbow turban to the San Diego Pride last year, but reshared it on Twitter for this year's Pride Month.
There were a few people asking where they can get their own rainbow turban. Kohli in response, said he wanted them to know that turbans were a responsibility for Sikhs and it's not the same as throwing on a rainbow hat.
"I wouldn't want people to have the impression that I'm just wearing it as an accessory," he said. "A turban is a sign to the world that you're a person the world can turn to for help."
Kohli also runs a website called "Bearded Baker Co", where he showcases his culinary prowess along with recipes for those who want to give his food a try.
