Blue is the Warmest Color is a quiet character study and romance unlocked by its title alone. Adele, a high school student focusing on literature, tries to fit in by dating the boy everyone knows she’s perfect for. She feels nothing from the relationship and winds up meeting Emma, a university fine arts student, at a lesbian bar. Emma’s bright blue hair catches her interest and helps her begin to form a sense of identity.
The color blue is important to the film. It really is a subtle device reflecting Adele’s self actualization. In the beginning of the film, when Adele is just following whatever her friends and family expect her to do, there is very little blue on the screen. The first memorable appearance of blue is a cross, Romeo & Juliet style, where Adele and Emma’s eyes meet while crossing the street and pass without incident. A bit more blue begins to fill Adele’s life as the thought of the beautiful stranger with blue hair sends her into sensory overload. The color blue grows and fades in shade (light blue is tepid, cyan is vivid, navy is overwhelming) and vibrancy to reflect Adele’s mental state and feeling of independence.
It really is quite remarkable how that kind of detail can set the tone for a film. By the time her high school friends realize Adele is a lesbian, you can’t avoid blue on the screen. Everyone is wearing dark wash jeans and vibrant scarves and hats. The sky is practically glowing and even the lockers in the school seem to transform. The dialogue is so simultaneously slice of life and driven by references to very specific philosophers, writers, and artists that the color conceit really opens up the text.
