Colour palettes that separate heroines from villains
Launch library · evergreen read

Costume designers frequently use colour as a quiet moral signal, dressing sympathetic characters in warmer or softer tones and antagonists in cooler, harder or more saturated colours, a convention subtle enough that most audiences absorb it without consciously noticing, yet consistent enough to shape how they feel about a character from their very first appearance.
This is rarely as simple as a fixed rule, since a compelling villain might occasionally wear rich, seductive colour precisely to seem dangerously appealing rather than obviously threatening, while a heroine's palette might darken temporarily during a period of hardship or moral compromise within her own personal arc across the story.
Colour choices are also planned relative to the rest of the frame, a heroine's costume chosen partly for how it will contrast against a set's background or a rival character's clothing, ensuring the eye is drawn exactly where the story needs attention at any given dramatic moment in a scene.
This careful, considered use of colour is one of costume design's most powerful and least visible tools, quietly steering audience sympathy long before a character's actions have fully revealed who they really are underneath the surface, for better or for worse, scene after scene, right through to the closing credits.
