Yellow blanket on the couch. Along with other decorations that are blue or yellow.

Blue hoodie, yellow ouija board.

Eddie in church "testing the waters" was blue and Buck looking for answer was yellow, so they were in each other colors while looking.

Return of the genuine beer. And this is big because the beer Eddie is drinking in the beginning has no brand.

Eddie was wearing the Buck watch for the church and the oferenda, but not for Abuela's death.

That puts him in black from head to toe for the parade. His talk with Pepa is the same color palette as the coming out scene and 809.

Buck's blue light shining on Eddie at the parade.

The yellow elements in the oferenda, along with the way all the windows are blue. A lot of it would be considered orange, but there is enough yellow.

Chris' room is blue now. It used to be cream.

Buck had a couple split blue and yellow moments.

But the house is no longer lit in yellow when Buck loses his faith.

Demon call that was clearly paralleling Eddie's struggle, the girl is dressed in yellow, the priest is blue. (I could write a whole essay on this but it would probably only make sense to Kym lol)

The snikerdoodles in the oferenda.

Buck's wip heart and then Abuela saying that's where Eddie will find the answers, and then Eddie and Chris touching the same spot.

Buddie fight at the station is obviously reminiscent of the 306 fight, but also the 511 fight.

That's all I can put into words and not sound like a maniac. Not that this doesn't sound insane to me anyway lol.

Explanation on the Buck watch and the genuine beer can be found on the blue and yellow masterpost. The masterpost will probably have all the answers surrounding the blue and yellow up until now. I also have a post on Eddie and black inside the blue and yellow.
