The sweet detail behind King Charles' Christmas trees seen in rare tour of royal homes

The sweet detail behind King Charles' Christmas trees at the Royal Family's official residences can be seen in a special new video giving a tour of the festive decorations at Windsor Castle and the Palace of Holyroodhouse.

• A virtual tour showing off the elaborate Christmas tree decorations at Windsor Castle and the Palace of Holyroodhouse has been shared on social media.
• It appears that there is a theme behind the color scheme of each tree, with the rare glimpse leaving royal fans in awe. 
• In other royal news, the Queen's GENIUS way of eating mince pies was revealed and we can't wait to try it. 

While King Charles, Queen Consort Camilla and key members of the royal family are preparing to celebrate a traditional royal Christmas at Sandringham, the King's other official royal residences aren't missing out on the elaborate festive decor.

A video clip posted on the Royal Collection Trust Instagram shared footage of the Christmas trees in St George's Hall at Windsor Castle, the Crimson Drawing Room at Windsor Castle, The Great Gallery at Holyrood Palace and the Throne Room at Holyrood Palace. 

"Let us take you on a quick tour of the royal Christmas trees," a caption in the video reads as a lively rendition of Jingle Bells plays.

"Have you put your Christmas tree up yet? Both the Palace of Holyroodhouse and Windsor Castle are feeling festive now the decorations are up," the Instagram post continues.

Enamoured royal fans took to the comment section to swoon over the gorgeous decorations at the Edinburgh-based palace and iconic castle where Queen Elizabeth II spent much of her final year. 

"All of them are beautiful," one wrote, while a second added, "Spectacular!"

The color schemes of each tree appears to show that the decs on each spruce are kept in line with the interiors of the regal room they stand in. 

The Crimson Drawing Room tree boasts a gorgeous, deep red theme to match the gold and crimson space, while the St George's Hall tree features flashes of purple to match the plum-colored carpets in the room and the Holyrood Palace Throne Room tree sparkles with gold and deep maroon to match the interiors of the special corner of the residence. 

No doubt the inside of Sandringham House will be looking equally festive currently, with King Charles set to host his first Christmas as monarch, following the death of Queen Elizabeth II in September. 

While the monarchy are predicted to continue the long-held royal Christmas traditions loved by Her Majesty the Queen, it's been predicted that things could change a little this year. 

Royal journalist Jennie Bond said, "It will be full of nostalgia and some good measure of sadness. There’s going to be that empty place where the Queen sat." 

Speaking to OK!, she added, "I think the King’s Christmas plans might be up in the air a bit.

"The younger royals will probably want to spend time with their own families, so I think the two or three day celebrations of the past may, indeed, be a thing of the past."
