What is the 3 color rule in UI?

The “3 color rule” in UI design is a guideline that helps create a visually appealing and coherent interface by limiting the palette to three main colors. This approach simplifies design decisions, improves user experience, and ensures consistency throughout the interface.

The three colors typically include

  • Primary color: This is the main color associated with your brand or product, used most dominantly throughout the UI. It should reflect your brand identity and be used for key elements like navigation bars, buttons, and links to draw attention and provide consistency.
  • Secondary color: This color complements the primary color and is used for secondary elements in the UI. It provides contrast and hierarchy, helping to differentiate between different sections or elements without overwhelming the user. The secondary color is usually a less dominant shade that still aligns with the overall design and brand palette.
  • Accent color: Used sparingly, the accent color is meant to highlight important actions or information, such as call-to-action buttons or alerts. This color should stand out against both the primary and secondary colors to draw the user’s attention to specific areas or functions.

Adhering to the 3 color rule helps maintain visual balance and harmony in the design, making the interface more intuitive and pleasant for users. This principle is central to creating effective and aesthetically pleasing UIs and is a fundamental concept in color theory for design.
