Dark mode isn’t just a trend – it’s a must-have for apps and websites. It helps users avoid eye strain, saves battery life (and looks great!). But creating a dark mode isn’t as simple as flipping colors.
If you want to do it right, especially for users who browse at night, you must consider user experience (UX). It’s not just about switching a few colors; it’s about making the experience feel natural and intuitive for the user. By doing so, you’ll improve accessibility and user satisfaction.
Here’s how to design a dark mode that works and feels natural for the people using it.

Why Dark Mode Matters
Dark mode is not just about looks – it’s about functionality.
Many people prefer dark mode because it reduces glare and makes screens easier on the eyes, especially in low light environments. For those who browse or work at night for hours, dark mode can make a big difference. Not only does it help reduce fatigue, but it also enhances focus, as users don’t have to squint or endure the harsh brightness of traditional modes.
Let’s get into some critical UX considerations for building a proper dark mode.
Color Palette in Dark Mode
Flipping black and white won’t cut it when switching to dark mode.
You need to think about the entire color scheme in terms of readability and comfort. The right combination of background and text colors ensures that your users have a pleasant experience without eye strain.
Contrast and Readability
You need the right balance of contrast. Text that’s too bright on a dark background can be just as painful as light mode. This can make reading uncomfortable, especially during prolonged use. Finding that sweet spot is key to user comfort.
According to Web Content Accessibility Guidelines (WCAG), the contrast ratio for text in dark mode should be at least 4.5:1 so your text is readable without being blinding.
A proper contrast ratio enhances legibility, making sure users don’t have to work harder to read the content. Keeping this in mind will ensure that your design remains inclusive and accessible.
Accent Colors
Accent colors like buttons or links should stand out but not overpower the design. Bright neon might seem fun, but it’s harsh at night. Subtle blues or greens work better.
These softer tones are easier on the eyes while still providing clear direction to interactive elements. Properly designed accent colors also maintain visual harmony across the app.
They guide users without causing distractions, enhancing the flow of interaction in your app.
Background Shades
Pure black might seem like the obvious choice, but it’s too harsh. It’s important to avoid overly stark contrasts that might cause discomfort over time.
Dark gray (#121212) is easier on the eyes and creates a smoother visual experience. It’s the shade used by apps like Slack and Spotify.
This shade reduces the potential for visual fatigue, especially for users who are engaged for longer periods. Dark gray helps to create a more balanced and pleasant viewing environment.
Typography for Dark Mode
Before we get into specific font tips here’s the deal: not all fonts work in dark mode.
Some fonts lose readability against a dark background, especially thinner or more decorative styles.
It’s essential to choose fonts with proper weight and legibility for optimal readability. Certain fonts just don’t contrast well against dark themes, so choosing the right one is crucial for user experience.
Font Weight and Size
Use slightly thicker font weights so letters don’t fade into the background. Aim for at least 16px for body text to be readable.
The font weight ensures that the text is clearly visible and maintains readability. It’s essential to avoid fonts that are too thin or light, as they can blend with the background in dark mode.
For the best results, consider using medium or bold fonts to ensure users can easily read the text without straining their eyes.
Line Spacing
Give your text some space. Increasing line height to 1.5x font size makes it more comfortable to read long blocks of text, especially at night.
Proper line spacing ensures that the text feels airy and doesn’t appear cramped. When reading in dark mode, adequate spacing is vital to maintain visual clarity and reduce eye strain.
This also helps users follow content more easily, keeping them engaged without feeling overwhelmed by the layout.
Reducing Eye Strain
The main goal of dark mode is to reduce eye strain, but it takes more than just dimming the screen to achieve that.
While dimming reduces brightness, it’s also important to manage contrast, color, and layout to create an overall soothing experience.
Think of dark mode as a way to create a harmonious balance between aesthetic design and comfort.
Blue Light Reduction
According to Harvard Health, blue light can disrupt sleep cycles.
When users interact with your app late at night, blue light emission can make it harder for them to fall asleep.
Adding a warm tint option in dark mode, like Apple’s Night Shift, can help users relax and sleep better after late-night app use. This gives users more control over their experience, helping them adjust the app’s settings to suit their personal preferences. It can also improve user satisfaction by offering features that prioritize health and well-being.
Animations and Motion
Bright, flashing animations in dark mode are harsh and counterintuitive.
Animations should be subtle and smooth to avoid disturbing the user experience. Excessive motion or flashing elements can be distracting and uncomfortable, especially in dark mode.
Go for subtle, smooth animations instead and keep the experience calm and user-friendly like dark mode.
Animations should feel natural and not compete with any content. A well-timed transition or gentle fade can create a more pleasant interaction, while unnecessary motion should be avoided.
Avoiding Pure Black Overuse
While pure black backgrounds might seem ideal, they can cause sharp contrasts that tire the eyes quickly.
It’s important to use pure black sparingly. Long exposure to high-contrast settings can cause discomfort for users.
Using deep gray tones, such as #121212, can provide a softer, more comfortable viewing experience, especially during extended use. By choosing a dark gray instead of black, you create a design that feels gentler and more pleasant without sacrificing the dark mode aesthetic.
Contextual Use of Dark Mode
Now that we’ve covered the basics, let’s talk about when and how to use dark mode. Dark mode isn’t just about applying a design style; it’s about providing a personalized experience for users.
Let users decide when dark mode turns on.
Allowing users to toggle between light and dark modes based on their preference ensures they feel in control of their experience. Apps like Twitter allow for automatic switching based on system preferences or time of day. This small detail shows you’ve thought about their convenience.
Allowing users to sync dark mode with the system clock is a great way to enhance usability without forcing them to change settings manually. Night owls often browse sensitive content or work late into the night. In these cases, dark mode can help reduce glare and make the experience less stressful for their eyes.
Encourage privacy with tools like a downloadable VPN; not only does it protect data, but it also enhances user trust in your app’s security features. This combination of features shows that you prioritize both user comfort and safety, creating a more secure and enjoyable experience for your audience.
Dark Mode Testing
Before you launch dark mode, you need to test thoroughly to make sure it works in all scenarios.
Testing across devices and environments is critical to ensure that your dark mode performs well in different contexts.
User Feedback
Get beta testers to use dark mode at night, in bright and dim environments.
Beta testing helps identify real-world usability issues and gives valuable insight into how users interact with your app.
They will find issues you missed, like contrast or readability problems, that will make the final design better.
Testing also helps ensure that the dark mode is optimized for a variety of user needs, from different lighting conditions to accessibility requirements.
Device Testing
Dark mode can be very different between devices.
Different screen technologies, such as OLED and LCD, display dark mode content in unique ways, requiring designers to account for device variability.
Test it on OLED and LCD screens to make sure it works the same, as lighting, contrast and color accuracy will be different. By testing on a variety of devices, you ensure that the dark mode provides a consistent and high-quality experience for all users.
This will make it a smooth and user-friendly experience for everyone.
Conclusion
Dark mode is more than a design trend; it’s about user comfort, especially for those who burn the midnight oil.
By focusing on contrast, typography, eye strain reduction and thoughtful implementation, you can create a dark mode that truly shines – well, not too bright!
