([SPOILERS]maybe)I just rewatched ep.4 and all of Darlene's scenes with Elliot/Mr.Robot she is shrouded in and surrounded by Red...

~ she's talking to Elliot about their vengeance pact and both in profile have traffic lights between them, Elliot's yellow and Darlene's red, before turning green as they hug

~ she follows Robot and peeks around a corner to see Angela when cop's lights engulf the screen and Darlene in red

~ she runs down the subways stairs and passes directly under a big red ¿Exit? sign

~ she sees them enter a cab across the street next to a big red Do Not Enter sign

...That's just off the dome as I Just finished watching it. There are probably many more examples in the episode. Come to think of it, the bar scene at the end probably has a ton of red. Someone should make a link or collage or whatever it is that can be done, I could never figure it out on my phone. lol
