Well, in the end it’s all artistic choice. They’re telling you which can fit your themes. But you could also change that. Look at blue is the warmest color. Blue was love, lust, comfort—it was really just the strength of their relationship. As the blue disappeared from the movie, their bond was breaking apart.
It’s all subjective to the filmmaker. Choose what makes sense for your story and stick to it. Then it could be added to this list.
The three left-hand pictures all subverted the trope too. Umbridge has a black heart, Rizzo is the least innocent girl in that movie, and the ski mask women scene is from a montage of crimes in a fairly dark comedy.
Yeah but I also think the filmmakers are using these colors in clear contrast of the character to show intentional conflict or deception of the character in question
