The Dangers of Ignoring Dark Mode in UI/UX Design

The Dangers of Ignoring Dark Mode in UIUX Design

A design trend we have noticed is attending to dark mode, an option with a dark background and light text and elements. Incorporating dark mode into your design strategy, you acknowledge the diverse needs of your users, ultimately leading to a more inclusive and personalized user experience. Ignoring dark mode can have several detrimental effects on user experience, accessibility, and overall engagement. Here’s why dark mode is important in modern UI/UX design.

One of the primary reasons dark mode has become popular is its impact on user comfort. Bright screens sometimes cause eye strain, especially in low-light environments. Many work-at-home professionals do not benefit from some office spaces’ optimal lighting environments. With that variability in lighting scenarios, dark mode is a valuable and necessary option. 

Dark mode reduces the light emitted by device screens, making it easier for the eyes to use during prolonged use. By ignoring dark mode, designers risk alienating users who prefer this more comfortable viewing option, potentially driving them to competitors who offer this feature.

Dark mode can significantly improve battery life for devices with OLED and AMOLED screens. These screens consume less power when displaying dark pixels than bright ones. Ignoring dark mode in design can lead to faster battery drain, particularly on mobile devices, resulting in a suboptimal user experience. Users may favor applications that help conserve their device’s battery life, giving dark mode-enabled apps a competitive edge.

Dark mode is not just a preference setting but a necessity for some users. Individuals with specific visual impairments, photophobia, or light sensitivity find dark mode more accessible. By neglecting to offer a dark mode option, designers fail to create inclusive experiences that cater to all users. Not attending to this user group can result in losing a significant user base who might find the standard bright interface unusable or uncomfortable.

Aesthetically, dark mode provides a sleek and modern look that many users find appealing. It’s associated with premium design and can make content stand out more starkly against the dark background. Ignoring dark mode might make your application or website appear outdated or less sophisticated. Catering to user preferences by offering light and dark modes can enhance satisfaction and loyalty.

As major tech companies like Apple, Google, and Microsoft have integrated dark mode into their operating systems and applications, users have come to expect this option. Ignoring dark mode can make your product seem out of touch with current market standards. Users now look for dark mode as a standard feature, and designers must account for this preference in their designs. 

Implementing Dark Mode: Best Practices

To successfully implement dark mode, consider the following best practices:

Consistency: Ensure dark mode is consistent across all elements and screens within your application.

Contrast and Readability: Maintain high contrast between text and background to ensure readability. Avoid pure black (#000000) and use dark shades of grey to reduce eye strain further.

Test Thoroughly: Conduct user testing to identify any issues specific to dark mode and gather feedback from users who prefer this mode.

Adding Dark Mode to an Existing Site

Implementing dark mode in an existing site requires careful planning and execution. By using CSS variables, ensuring high contrast, and providing a user-friendly toggle, you can retrofit dark mode without compromising the user experience. This update involves thoughtful planning and implementation to ensure a seamless user experience without breaking the site. 

Here are some necessary steps and best practices to follow:

Start by auditing your current design elements and styles. Identify all the components, including text, backgrounds, buttons, and images, that need adjustments for dark mode.

CSS variables (also known as custom properties) allow for dynamic theming. At the root level of your CSS, define color variables for both light and dark modes.

Allow users to switch between light and dark modes with a simple toggle button. Use JavaScript to add or remove a dark-mode class to the body element based on the user’s choice.

Ensure optimization of images and media for both themes. Use transparent PNGs or SVGs where possible, and consider creating dark mode-specific versions of images if necessary.

High contrast is crucial for readability in dark mode. Use tools like the WebAIM Contrast Checker to ensure that your text and UI elements meet accessibility standards.

Roll out dark mode gradually, starting with a beta version for a select group of users. Gather feedback to identify any issues or areas for improvement before a full-scale release.

Use local storage to remember the user’s theme preference across sessions.

Conduct thorough testing across different devices and browsers to ensure that dark mode functions correctly and that there are no regressions in the user experience.

Document your changes and communicate with your development and design teams to ensure everyone is on the same page. Clear documentation will help maintain consistency and aid future updates.


Ignoring dark mode in UI/UX design can have significant negative consequences, from reduced user comfort and accessibility to shorter battery life and diminished user engagement. As dark mode continues gaining popularity, designers must incorporate this feature to meet user expectations and provide a holistic, inclusive user experience. By embracing dark mode, you enhance the aesthetic appeal of your product and cater to a broader audience, ensuring your application remains competitive, user-friendly, and scalable.
