Duke and Duchess of Sussex have only published Archie's images on two different occasions so far, both times refusing to make the fans clear. The first image of Little Archie was revealed to the world, two days after it was born on May 6. Archie was retained in the arms of his father Harry, while wearing a white cotton cap.
Two weeks ago, the duke and the duchess sent a second photo to their Instagram Royal de Sussex for the day of their father.
But royal supporters were once against the left after the edge wire was stored in a black and white filter.
However, photo experts believe they have solved the mystery after analyzing Archie's images as of June 16.
Jordan Lloyd of Dynamichrome, who specializes in high-fidelity color reconstruction, said Archie's "mixed heritage" was "quite unlikely" to follow his father's genetics and have hair of ginger
Mr. Lloyd said that Archie's hair color is more likely to shorten with age and be brown.
He told the Daily Star Online: "As with any black and white photograph, we can infer some details with additional information and look at the tonal values to make an educated conjecture.
"Obviously, I can not see the future and the genetics of hair color is a complex issue, so this is just an opinion."
He added: "Looking at this picture, we can see that Archie's hair is very fair and hair in babies tends to be lighter or darker during the first three years before reaching the reverse.
"If I were to make a conjecture, we are seeing a blond light now that it can become darker with age, but given the mixed inheritance of the duchess, it is quite unlikely that Archie's hair will be ginger like the Prince Harry, since ginger is a recessive gene.
"I suppose it will be brown, but only time will tell".
