A video of Claire Foy refusing to sign autographs with a blue pen has sparked a debate on social media.
A clip of the 39-year-old British actress - best known for starring as young Queen Elizabeth II in the Netflix drama series The Crown - has made rounds on the internet and left many people confused.
In the video shared on TikTok, a man offers Foy paper and a blue pen to sign her name with, but after spotting the marker's color, she's heard saying: "I don’t do blue."
"What?" the man responds, seemingly taken aback by her reply, as she repeats her statement for the individual.
Watch the TikTok below:The Season of the Witch actress is then approached by another fan holding a black Sharpie and stops for them so that she can sign their white paper.
And this isn't the first time Foy has been spotted rejecting a blue Sharpie - as she can also be seen doing the exact same thing in the video below:
Under the footage - shared by TikToker MickMickNYC - viewers were quick to speculate why the Golden Globe winner refused to touch the blue pen.
"That is the weirdest thing! No blue, wonder what the reason is?", one person reacted, while another said: "I need to know why she doesn’t do blue?!?"
Many users shut down claims of the award-winning actress being impolite, saying her dismissal of the fan had more to do with her not wanting her autograph to be sold.
"Most celebrities and athletes are taught not to do blue ink cause you can scan and forge the signature on other things and sell them," one user explained.
Another added: "For computer scanning recognition it’s used to forge," while someone else said: "Apparently, blue ink allows people to transfer signatures easily to other items which is why they only sign with black ink."
"Colored ink autographs get sold for far more money on eBay etc. Some celebs don’t want to support a secondary market/exploitation of their brand," someone else penned on Instagram.
Last year, basketball star Russell Westbrook was also seen refusing to sign an autograph with a blue pen.
After Russell was criticized on social media, fellow basketballer Patrick Beverly explained on his podcast 'The Pat Bev Podcast with Rone' that he’d also been warned to avoid signing anything with a blue pen.
"I was taught, maybe after my third year that you’re not supposed to use a blue pen because they can use that signature and slap it on another jersey and sell that, but you can’t do that with a black pen or grey pen," he explained.
So the next time you want a celebrity to sign something, remember to keep a black pen in your bag.
