Semantic Terms for UI Design: Colors

Aug 24, 2023 • 5 min read

In the world of design and user interfaces, there’s a rich vocabulary of terms that help professionals communicate ideas, concepts, and strategies.

These are semantic terms that encapsulate specific design attributes, allowing for seamless communication across the design and development spectrum.

Let’s delve into the meanings behind some frequently used semantic terms for colors in UI Design.


Primary colors form the bedrock of a design’s color palette.

They are the dominant hues that represent a brand’s identity and set the tone for the entire visual experience. Think of primary colors as the building blocks from which all other colors are derived.

These colors often evoke emotions and contribute to brand recognition, making them a pivotal aspect of any design endeavor.


Secondary colors are the companions to primary colors.

Chosen to complement and enhance the primary hues, secondary colors offer versatility and balance to a design. While primary colors capture attention, secondary colors provide visual interest and help differentiate various elements within a user interface.

This interplay between primary and secondary colors creates a harmonious and engaging visual experience.


Accent colors hold the power of emphasis in a design.

These colors are strategically selected to draw the user’s attention to specific elements, actions, or information.

Often used sparingly, accent colors stand out against the primary and secondary colors, serving as visual cues for call-to-action buttons, alerts, and interactive components. Their judicious use helps guide users through the interface while reinforcing brand identity.

Additionally, an accent color can be used to reinforce a brand identity or to evoke certain emotions or associations. When chosen thoughtfully, an accent color can communicate energy, urgency, trust, or any other desired attribute. It helps establish a memorable visual identity for a product or brand.

It is important to note that accent colors should be used sparingly and purposefully to maintain balance and prevent visual overload.

Overusing or applying accent colors inconsistently can lead to a chaotic and confusing user interface.


Emphasis colors highlight specific elements within a user interface. These colors would typically be different from the primary, secondary, and accent colors used in the UI.

They draw attention to critical elements such as important information, error messages, or warnings, helping visually distinguish these elements from the rest of the interface and ensures they are noticed by users.

The choice of an emphasis color would depend on the overall color palette and design scheme of the UI. It could be a vibrant or contrasting color that stands out prominently against the background or surrounding elements.

By using an emphasis color selectively and purposefully, designers can effectively communicate the importance or urgency of specific UI components or actions.


Muted colors hold a special place in design for their ability to create understated elegance.

In UI design, muted colors are commonly used for various purposes, including:

  1. Backgrounds: Muted colors are often applied as background colors to create a subtle and less distracting backdrop for the UI elements. This helps to bring focus to the foreground content or more important design elements.
  2. Text and Typography: Muted colors can be utilized for text and typography to provide a softer and more relaxed reading experience. They can be particularly effective for large bodies of text or for conveying a sense of elegance and sophistication.
  3. Non-critical Elements: Muted colors are frequently used non-critical information that don’t require immediate attention or are less prominent. They help to differentiate these elements from primary or interactive components.
  4. Highlights: Muted colors can also serve as subtle highlights in UI design. By using muted versions of primary or secondary colors, designers can add visual interest and depth to the interface without overwhelming the user.

These desaturated or softened hues offer a calmer visual effect, evoking a sense of nostalgia and sophistication and contributing to a balanced and cohesive design. They provide a subdued backdrop for more prominent design elements.


Subtle colors are typically less saturated or have lower contrast compared to the more prominent or attention-grabbing colors used in the UI.

They are used to create a calm and cohesive visual experience, allowing the more important elements to stand out without overwhelming the user.

Some common uses of subtle colors in a UI include:

  1. Backgrounds: Subtle colors are often applied to the background of a UI element, such as the overall page background or the background of panels, cards, or sections. This helps create a neutral or calming backdrop that allows the foreground content to be the main focus.
  2. Borders and Dividers: Subtle colors can be used for borders and dividers between UI elements to provide separation and structure without being visually distracting.
  3. Supporting Elements: Subtle colors can be utilized for secondary or supporting UI elements that don’t require immediate attention, such as secondary buttons, form fields, or non-critical information. This allows the more important elements to take center stage.
  4. Disabled or Inactive States: Subtle colors may be employed to indicate disabled or inactive states of UI components, such as grayed-out buttons or inactive tabs. This communicates to the user that the particular element is not currently available for interaction.

The purpose of using subtle colors in a UI is to create a visually pleasing and balanced interface that doesn’t overwhelm the user.

By carefully selecting and applying subtle colors, designers can establish a cohesive and harmonious visual experience, enhancing usability and overall user satisfaction.
