You've probably never noticed this weird detail in almost every Home Alone scene.

Well, here’s a fun festive one for you.

It seems we’ve all been missing a crucial detail in Home Alone, even though we’ve watched it approximately 496096 times.

And it all has to do with… colour coordination.

You see, a journalist named Claire Reilly was recently re-watching the movie when she noticed something odd in the background of almost every shot.

The movie is set at Christmas time, so the McAllister’s house is covered in Christmas decorations and lights and a giant Christmas tree. But if you look closely, you’ll notice that underneath all that Christmas cheer, the whole house is actually decked out in red and green.

The wallpaper is red. The walls are painted green. The pots in the kitchen are red. Even the phone is green.

You can read Claire’s entire thread here:

Can we talk about the McAllister’s house in Home Alone for a second? Like, of COURSE you’re going to be a target for Christmas bandits if your house is ENTIRELY Christmas themed! Okay, yes, they have a lot of Christmas decorations up, but that is JUST THE START… pic.twitter.com/9EN0SNyGJ2

Look at that wallpaper. What kind of monster has red wallpaper next to a green wall? Offset with contrasting green house plant and red candles? pic.twitter.com/9Lxm1ewfGv

Throw up a festive green tapestry in the green corridor on the way to your attic, why not! pic.twitter.com/SuKru6caDw

Yes, it’s the 90s, but who has a green LANDLINE PHONE? With red, white and green wallpaper? And red flowers hanging from the bed above red pillows? Did they cast Catherine O’Hara purely because of her red hair? This goes all the way to the top… pic.twitter.com/cYv7eTJMKK

“Tell the truth. Did you just decorate this place as an elaborate con to leave me at Christmas time?” pic.twitter.com/7fF99qb5Kh

But WORST of all is the kitchen. Red pots, green tiles, red teapot, crimson floors, even a green rolling pin. Guys. We all go to the themed sections of IKEA and get ideas, but you’re not supposed to do it in real life.

Home Alone: Great movie. Decorator’s nightmare.

Okay, one more, just for good measure.

Merry Christmas ya filthy animals. pic.twitter.com/VZ24TLz1E1

Understandably the thread has blown people’s Christmassy minds.

That bothered me, too — especially because they weren’t going to be home for Christmas! No wonder they forgot a kid; they’re exhausted from unnecessary decorating!

It took 28 years for this to be noticed but now it can’t be unseen. Great. Can’t wait to watch Home Alone at some point this month. #TotalDistraction ????

Also they weren’t even going to be AT home for Christmas. Why be so extra about the whole thing? ????????????

I’m watching Home Alone now and cannot unsee all the Christmas themed decor. New drinking game: drink every time you see an innocuous item unnecessarily Christmased out.

My whole life has been a lie.
