Fans watching last night's episode of The Graham Norton Show were left frustrated by the fashion choices of one prominent musician as Pharrell Williams took a seat for an interview.

Pharrell made an appearance on Graham's show, joining a star-filled lineup that included Billy Crystal and Paddington, with Emily Mortimer and Hugh Bonneville, who are both featured in the movie set in Peru.

The musician, who has won a Grammy, was in town at the age of 51 to promote his latest biographical film, Piece By Piece.

The animated movie depicts Pharrell's journey to stardom in a Lego representation, highlighting the making of his popular 2014 track, "Smile."

In his conversation with Graham, Pharrell shared his experiences with synesthesia—a sensory condition that enables him to perceive various sounds as colors.

Nonetheless, the celebrity put off some fans by wearing a baseball cap and sunglasses during his appearance.

As the episode was broadcast, fans took to social media to express their annoyance at what they saw as the star's mistake.

"Why is Pharrell sporting sunglasses on the #GrahamNortonShow? I get that he's stylish, but come on!" tweeted user MichZiff.

"Sunglasses – seriously uncool. (Unless there's a health issue involved),” concurred robstowers.

"Why is he wearing sunglasses? That's such poor etiquette," commented captmagenta.

"Why is Pharrell Williams wearing sunglasses on the Graham Norton show? You're making me blush in front of Billy Crystal," lamented kimwexlcrs.

While the star was presenting his latest film, Graham asked him about the medical condition known as synesthesia, which is discussed in a clip from the movie.

In a segment from Piece By Piece, Pharrell shared his childhood experience of synesthesia through narration.

"It's not something you can see with your actual eyes; it's more of a vision that you perceive in your imagination," the star clarified.

For example, you might picture Pharrell's Lego brick character stepping into a lively swirl of colors, where sound and music merge harmoniously.

"Is this how you react to your senses, or do your senses function a bit differently?" Graham questioned while they were back in the studio.

"That's right," Pharrell explained. "The most well-known type is linking sound to color, but there are many forms of synesthesia in existence. Essentially, synesthesia occurs because when we are born, our sensory nerve endings are intertwined."

"When you reach a certain point, they trim back the branches. Occasionally, they don't remove everything completely. This creates a situation similar to a flaw, where two nerve endings remain connected."

He went on to explain, "For me, it was all about vision and hearing. Each nerve ending would transmit phantom images to various areas of my brain. So when I hear sounds, I also see colors."

"This isn't some extraordinary talent like that of Albert Einstein, alright? It's something that many artists, particularly musicians, experience frequently."

Although the creator of "Get Lucky" hasn't confirmed whether his accessory choice has anything to do with his condition, it’s known that people with synesthesia often face sensory overload. In some instances, tinted glasses can help manage this.

Boston University reports that the condition affects about 1 in every 5,000 individuals. Other variations of this condition include the ability to "taste" specific words or "see" colors associated with different days of the week.

The fashionable celebrity, who has his own clothing brand called Icecream, is recognized for his love of sunglasses. He even worked with Louis Vuitton to create his own design. So, this choice might have been driven solely by a sense of style.

He follows a tradition of American celebrities who have turned up to interviews in sunglasses, such as Zac Efron on The Today Show and Kevin Hart on The Late Show.

While sitting on Graham's sofa, Pharrell shared his perspective on how many CEOs and successful entrepreneurs often have some level of ADD or ADHD.

"There's definitely value in those who are unique from the start. In my view, your differences are what make you stand out and truly special, and that's the central theme of this movie."
