Sorry this has taken so long for me to get to - I had to think about it for a while, and color is BCS is a really big subject, so I'm probably going to make separate posts rather than just jamming everything into one. I'll use the tag #bcs color theory.

(Side note: I know that there have been interviews about the use of color, but I'm very bad at remembering them - if anyone has links, I'd be interested in them!)

So first up, let's talk about red. Blue = heroic and Red = evil doesn't really pan out. The two characters who commit the most evil acts and are the most unrepentant criminals, Gus and Lalo, almost never wear red. Mike, another committed criminal, also doesn't wear red. (On the other end, Chuck is most often associated with blue, and he's not exactly a paragon of goodness.) The character most associated with red is Nacho, who I think you'd have a pretty hard time arguing is meant to be the embodiment of evil.

Instead, red is a color of deceit. Nacho's storylines all revolve around deception and backstabbing, sometimes of his own volition, like with Tuco and Hector, and sometimes forced, as when Gus blackmails him into spying on Lalo. And it would probably be easier to make a list of scenes where he doesn't wear red than when he does.

The other character most closely associated with red is...Betsy Kettleman, a character who literally never tells the truth.

In Kim and Jimmy's stories, red pops up when they are being deceitful. The shot in the darkroom from season 6 is pretty explicit with associating red with lies

And here's a shot from season 1 when Jimmy is lying to Kim

Then there's the bright red "LIE" of their alarm clock

Kim also starts to wear red in season 6 when the Ham Scam is in full gear

Pink, which really is just light red, is also associated with Jimmy and Kim when they are dishonest. Kim is wearing pink when the consequences of her lies finally catch up to her

She's also wearing pink when she tells Jimmy she wants to continue scamming

Jimmy wears pink when he's picking up Lalo's bail money, which he lies to Kim about what happened when he gets back

He wears pink when he starts embracing his Saul Goodman persona in earnest in season 5

I just mean, …this might not be what you dreamed of when you were twelve. @pscentral event 13: tropes

Both. It’s both.
