Red is Vecna’s powers and blue is Will’s?
Commonly in film blue represents the good, whereas red represents the bad. (Most common example being Star Wars).
Could Will be fighting back using blue forces against whatever Vecna is trying to do with the red explosions?
Here is the evidence that leads me to believe this…
@tryingonametaphor also mentioned that this supports the Will Byers created the Upside Down theory because the Upside Down is blue whereas Vecna’s lair is red!
Will is encompassed in red lighting in the picture below to the right as Vecna taunts him…
In this shot of Will below, we can see bright blue light take over as from the left side as he is in deep focus…
Maybe it is in this scene where Will becomes the ‘Sorcerer’…
Edit: @that-witchy-pan mentioned in the comments that Will’s powers in his painting are also blue!!!!
Edit 2: it could also be a political commentary of blue vs red…
Edit 3: I think that this theory can also go hand in hand with this since the red could mean the anger, and the blue could mean the love—especially if blue is Mike’s color and Will is in love with him. And in volume 1, his powers manifested when he saw Mike in danger, and Mike was the first memory he thought of in order to gain strength and find self-love.
Edit 4: Post volume 1 thoughts again, I’m also thinking that the red surge could have something to do with Vecna putting all 12 children on the spires. Dustin said that the lab is in the center of the wall, if all the kids are outside of the wall, or maybe even in the lab(?) the red surge erupts through the UD as all of them are where Vecna wants them to be and maybe that’s what causes Will to fall unconscious? Maybe the blue is Will trying to fight it or falling unconscious to it. Or maybe, something happens in Camazotz/Henry’s mindscape and that’s what causes the red surge, and Will is also in his mindscape at this time—so the blue surge erupts from him. Or maybe the red and blue surges don’t happen at the same time at all and it is a classic Duffers trailer misdirect.
