How to Design a Dark Mode in iOS

In today’s world, mobile devices are used extensively in various lighting conditions. While bright and vibrant interfaces excel in well-lit environments, they can become harsh and eye-straining in low-light situations. Dark mode, a user interface theme that utilizes a dark background with lighter text and elements, has emerged as a popular solution. This blog post equips you, the iOS app designer, with a comprehensive guide to designing for dark mode, ensuring your app delivers a comfortable and visually appealing experience regardless of the lighting conditions.

Understanding the Benefits of Dark Mode

Beyond aesthetics, dark mode offers several advantages for users:

Improved Eye Comfort: Dark backgrounds reduce screen glare and eye strain, especially when using your app in low-light environments. This is particularly beneficial for users who frequently interact with their devices at night.

Reduced Battery Consumption: On devices with OLED displays, dark mode can contribute to improved battery life. Since OLED pixels don’t require illumination for black colors, displaying a dark interface consumes less power compared to a bright one.

Enhanced User Experience: A well-designed dark mode can create a sleek and modern aesthetic, potentially enhancing the overall user experience of your app. Furthermore, dark mode can improve the legibility of certain content by creating a higher contrast between text and background.

Core Design Principles for Dark Mode

Before diving into specific design elements, consider these core principles:

Hierarchy and Contrast: Maintain a clear visual hierarchy in both light and dark modes. Utilize color contrast effectively to distinguish between different UI elements and ensure readability. While dark backgrounds are ideal, avoid using pure black and opt for dark gray tones to maintain sufficient contrast.

Color Palette Selection: Choose a color palette specifically designed for dark mode. Consider using a cool-toned palette to complement the dark background and avoid overly vibrant colors that might appear jarring.

Iconography and Images: Ensure your icons and images are optimized for both light and dark modes. Invert colors where appropriate, or consider creating separate icon sets for each mode.

Crafting a Seamless User Experience

Now, let’s delve into specific design considerations for common UI elements:

Navigation Bars: In dark mode, make navigation bars visually distinct from the background. Utilize lighter text colors and consider adding a subtle border for better separation.

Buttons: Maintain clear button functionality in dark mode. Utilize contrasting colors to highlight primary and secondary buttons and ensure sufficient contrast between text and button background.

Text and Text Styles: Prioritize readability in dark mode. Choose a light and easy-to-read font color with sufficient contrast against the dark background. Adjust text styles, including font size and weight, to ensure optimal legibility across various UI elements.

Forms and Input Fields: Design forms and input fields with clear visual cues in dark mode. Utilize lighter placeholder text and consider adding subtle outlines to input fields for better visibility.

Advanced Techniques for Dark Mode Mastery

For a truly exceptional dark mode experience, explore these advanced techniques:

Dynamic Color Usage: Leverage Apple’s Dynamic Color API to create colors that automatically adapt to both light and dark mode. This ensures a more seamless and consistent user experience.

Blur Effects: Utilize blur effects judiciously to create depth and separation between UI elements in dark mode. However, avoid excessive blurring, as it can make the interface appear cluttered.

Accessibility Testing: Rigorously test your app’s dark mode for accessibility compliance. Ensure sufficient color contrast for users with visual impairments and consider additional accessibility features to accommodate all users.


By embracing dark mode and following the design principles outlined above, you can create an iOS app that offers a comfortable and visually appealing experience in any lighting condition. Remember, prioritize user comfort and accessibility, while simultaneously maintaining a cohesive and aesthetically pleasing design. So, embrace the power of dark mode, illuminate the path to user comfort, and elevate your iOS app to the next level.
