Choosing UI colors involves strategic selection based on branding, user experience, and accessibility to create a visually appealing and functional interface.
Selecting the right UI colors is crucial for establishing brand identity, guiding user interaction, and ensuring readability. It starts with understanding your brand and the emotions you want to evoke.
Building Your UI Color Palette
A well-structured UI color palette typically includes a primary color, secondary colors, accent colors, and neutral colors.
1. Start with Your Primary Color
Begin by selecting your primary color. This color should ideally be one of the main colors associated with your brand. It will likely be the most dominant color in your interface, used for key elements like calls-to-action, primary navigation, and branding elements. Using your brand color helps reinforce recognition and consistency.
- Tip: Consider the emotional impact of your brand color. Does it convey trustworthiness, energy, sophistication, or something else?
2. Selecting Secondary and Accent Colors
- Secondary Colors: Choose one or two secondary colors that complement your primary color. These can be used for less critical elements, illustrations, or backgrounds, providing variety without overshadowing the primary color.
- Accent Colors: Select an accent color to highlight important elements that need to stand out, such as buttons, links, notifications, or key information. Accent colors should have sufficient contrast against their background and other colors.
3. Choosing Neutral Colors
Neutral colors like grays, whites, and blacks are essential for backgrounds, text, borders, and spacing. They provide structure and readability.
- Important Consideration: When dealing with backgrounds or large areas, avoid using absolute white (#FFFFFF) or black (#000000). Slightly off-white or dark gray shades are often softer on the eyes and provide better contrast control, especially with text.
Practical Tips for Choosing UI Colors
- Consider Color Psychology: Different colors evoke different emotions and associations. Understand what feelings your chosen colors communicate. For example, blue often suggests trust and stability, while green can represent growth or nature.
- Prioritize Accessibility: Ensure sufficient color contrast between text and background colors to make your interface readable for everyone, including users with visual impairments. Tools like online contrast checkers can help you verify compliance with accessibility standards (e.g., WCAG).
- Use a 60-30-10 Rule (Optional): A common technique is to allocate 60% of your design to your primary color (or neutral background), 30% to secondary colors, and 10% to accent colors. This provides visual balance.
- Test on Different Devices: Colors can appear differently on various screens and devices. Test your palette across desktops, tablets, and mobile phones to ensure consistency.
- Get Feedback: Share your color palette and mockups with others to get diverse perspectives.

Choosing a UI color palette is an iterative process. Start with your core colors and refine them based on testing, user feedback, and accessibility requirements. Referencing established design systems and color theory principles can also provide valuable guidance.
