Which design principle repeats one colour in a given area?

The design principle that repeats one color in a given area is referred to as repetition. This concept emphasizes the consistent use of a particular color throughout a design, helping to create cohesion and unity within the space. By utilizing repetition, a hairstylist can enhance the overall aesthetic, making it more harmonious and visually appealing.

In the context of hairstyling, this could manifest in the consistent use of a certain hair color across various sections or layers of hair, contributing to a unified look. Repetition aids in establishing brand identity, and it can guide the client’s eye through the design, creating a sense of balance.

The other choices hint at different concepts: alternation involves variations within a sequence, contrast highlights differences between elements, and progression refers to a gradual change or increase in characteristics. While all are important design principles, they do not specifically address the repetitive use of a single color like repetition does.
