Cerulean blue: 9 projects embrace the iconic color of "The Devil Wears Prada"

With the debut of "The Devil Wears Prada 2" on the agenda, some elements of the film are making the rounds again — among them, the well-known cerulean blue. The hue appears in one of the film's most memorable scenes and has become a recurring reference when it comes to the emergence of trends.

In the story, cerulean blue is presented as the result of a process that begins on the runways and, over time, reaches everyday consumption. This explanation links the color to a broader logic of creation, circulation, and appropriation – going beyond the boundaries of fashion and reaching the world of decor as well!

Remember the cerulean blue in "The Devil Wears Prada"?

The scene in question takes place at the Runway magazine office, when the character Miranda Priestly (Meryl Streep) chooses between two blue belt options for a photoshoot. Her assistant, Andy Sachs (Anne Hathaway), shows indifference to the colors of the piece. With that, the fashion editor pauses the decision to explain that the very cerulean blue sweater she is wearing is not a random choice – but the result of decisions made years earlier by top designers and absorbed by the industry!

By detailing how the shade emerged on the runways and was disseminated until it reached everyday apparel, the character reveals the complexity behind something that seems trivial. This framing helps us understand cerulean blue not only as a color, but as part of a cultural process. In decor, the same logic holds: when incorporated into projects, the shade carries a narrative that goes beyond aesthetics, connecting everyday choices to broader movements in design.

Different ways to incorporate it into decor

Cerulean blue can appear in a project in different ways, from targeted interventions to bolder choices, without compromising the coherence of the space.

Walls as a backdrop

Applied to walls, cerulean blue creates a continuous base that expands the perception of the project without making it feel heavy. It works especially well in living rooms and bedrooms, where the color can envelop the space in a subtle way.

Furniture as a highlight

Sofas, armchairs or consoles in this shade introduce cerulean blue as a focal point. In this case, the color organizes the project around it, harmonizing with more neutral materials.

Textiles and objects

Pillows, throws, rugs and decorative pieces let you introduce cerulean blue gradually. This approach creates visual layers without completely changing the base of the space.

Finishes and details

In kitchens and bathrooms, cerulean blue can appear in tiles or finishes, bringing freshness and lightness to the decor.

How to integrate the hue into projects

Integrating cerulean blue requires attention to combinations. The shade relates naturally to materials such as light wood, linen and natural fibers, creating compositions that highlight texture and light. When paired with neutrals, such as white, beige or soft gray, it reinforces a sense of balance and continuity.

Lighting also plays an important role. Natural light highlights the nuances of cerulean blue, while artificial lighting can warm or soften its presence. By considering these aspects, the color adapts to the project without excess, maintaining a fluid, lasting impression.
