Peter Gould @petergould .@batwood We have a new color code on #BetterCallSaul. As a rule, hotter colors are associated with crime. You figure out the rest. 02:59 AM - 24 Feb 2015 Reply Retweet Favorite "Figure out the rest" was exactly was Reddit user saulspiracy did. AMC The theory – known as the fire and ice theory – is simple: Hotter colours such as reds and oranges are associated with crime, while blues represent the good guys. So let's take a look at the evidence... First up, you can clearly see that the skater feigning the broken leg is wearing red, while the old woman they're trying to scam is in blue. AMC Of course the old lady turns out to be Tuco's grandmother. We know where he stands on the crime spectrum, so guess what colour he's wearing? AMC During negotiations between Nacho and him, there's clearly a good cop and a bad cop. AMC But when Nacho turns up later that episode to tell Jimmy about his plans to rob the Kettlemans, he's changed his shirt. AMC Talking of the Kettlemans, if you weren't certain of their guilt beforehand, look at the colour of their tent. AMC And of the bag full of embezzled government money. AMC The red tie on Jimmy's accomplice from this flashback was a sure sign that he was up to no good. AMC So who are the good guys? Well, Kim's shirt here shows that she's probably as sweet and innocent as we'd expected. AMC And what colour is Jimmy painting her toenails? Blue. The police too. AMC Not forgetting Mike, of course. AMC So what about Jimmy? In this flashback of Chuck visiting him in jail he's wearing nothing but red. AMC Flash-forward a few years, and he clearly wants to think of himself as one of the good guys. AMC In this scene he picks up an orange shirt, considers it, then puts it down. Hinting at his future. AMC When he knows about Nacho's plans but refuses to tell Kim, we see him bathed in red light. AMC But then when he finally does the right thing and warns the Kettlemans there's nothing but moonlight and a blue pay phone. AMC Even his car's unorthodox paint job hints at Jimmy's inner turmoil. AMC Speaking to Variety about the title character, Gould said: "Colorwise, he’s already bridging those worlds a little bit." Of course we know where Jimmy ends up, but how he gets there – and how long it will take – remains to be seen. AMC All you can be sure of for now is that anyone who turns up wearing red is probably going to speed the whole process up.
