Understanding dark colors in UI design

Dark UIs, often referred to as dark modes or themes, have gained immense popularity due to their visual appeal and potential benefits, such as reduced eye strain in low-light conditions and improved battery life on OLED and AMOLED screens. However, not all dark colors are created equal when it comes to UI design.

The best dark color for UI should enhance readability, reduce eye fatigue, and maintain the integrity of other design elements. It’s not just about choosing the darkest black available; it’s about finding a color that complements the overall design and enhances the user experience.

Choosing the right dark color

Deep blue or charcoal gray

Instead of pure black, consider using deep blue or charcoal gray. These colors are less harsh than pure black and can provide a sophisticated and modern look to your UI. They are easier on the eyes and make other colors, especially lighter ones, stand out without causing strain.

Contrast and accessibility

When selecting a dark color, ensure sufficient contrast with text and other elements. High contrast helps in readability and accessibility. The Web Content Accessibility Guidelines (WCAG) recommend a contrast ratio of at least 4.5:1 for normal text. Tools like WebAIM’s Color Contrast Checker can help in evaluating this.

Consistency with brand colors

The dark color you choose should align with your brand’s color palette. If your brand has specific colors, consider using a darkened version of these colors for your UI. This ensures brand consistency and recognition.

Testing across devices

Different devices and screens display colors differently. Test your chosen dark color across various devices to ensure it looks good and remains functional in different lighting conditions and screen settings.

Feedback and iteration

Collect feedback from users and stakeholders. Seeing how real users interact with the dark theme can provide insights into whether the chosen color works well or needs adjustment.

Benefits of using the right dark color

The correct dark color can significantly enhance the user experience. It can make the interface less glaring, especially in low-light environments, and can help users focus on the content without distractions. Moreover, it can contribute to battery saving on devices with OLED and AMOLED screens.


The best dark color for UI design depends on various factors, including brand identity, user needs, and environmental conditions. Deep blues and charcoal grays are generally excellent choices, offering a balanced mix of style, comfort, and readability. However, the ultimate choice should be informed by user feedback, accessibility standards, and consistent testing across different platforms and devices.

In the realm of digital product design, especially for UI targeting Figma users, embracing dark themes can be a game-changer. Not only does it cater to the aesthetic and practical preferences of users, but it also aligns with modern design trends favoring minimalism and dark aesthetics.

Remember, the key to a successful UI design lies in the details. So, choose your dark colors wisely, test them thoroughly, and always prioritize user experience and accessibility.
