Dark Mode in Web Design: The Pros, the Cons & the Best Practice

Jun 11, 2025 — Web Design & Development

If you’ve been surfing the web over the last few years, you’ll have definitely noticed one huge change: increasingly, websites and applications are introducing a dark mode option. It’s not a fad, it’s revolutionizing the way we use the web. But what’s actually driving the popularity of dark mode web design? Is it all about appearing cool, or is there something deeper? Let’s jump in and discover the actual pros, cons, and best practices of dark theme website design: all in simple human terms.

Why is Dark Mode so popular?
First, let us discuss what dark mode really is. Simply put, it’s a design where light elements and text show up on a dark ground, contrary to the typical light background with dark text. It’s now a darling among designers and users alike, and here’s why:

Easier on the Eyes:
Perhaps the largest reason users adore dark mode is that it’s easier on the eyes, particularly in low-light environments. If you’ve ever attempted to read a brightly lit screen in a dark environment, you’re aware of how awkward it feels. Dark mode web design minimizes that annoying glare, which makes browsing easier at night.

Saves Battery Life:
This is a huge one for mobile users. On OLED displays, dark pixels consume less power, so dark theme web design can really make your phone or tablet last longer on its charge.

Contemporary and Sleek:
Let’s face it: dark mode is simply cool. It makes websites look sleek, contemporary, and fresh and sophisticated. For companies that need to look innovative or technological, this can be a major plus.

Attentive Focus:
With less background noise, users will notice more what matters—your content, products, or services. This is one of the subtle but powerful benefits of dark mode UI design.

The Downsides: What to Watch out For
Of course, nothing is perfect. While dark mode has many fans, it’s not always the best option in every scenario. Here are some things to watch out for:

Readability Issues:
In light environments, reading light text over a dark background can in fact be more difficult. If your users are going to view your site in the daytime or in light offices, this is something to think about in your dark vs light mode UX design.

Not everyone Likes it:
Some simply like the plain appearance of light mode. Forcing all to dark mode can have an unintended rebound effect, so it’s wise to provide a toggle or allow users to select their preference.

Contrast Challenges
Getting the contrast correct is essential. Not enough contrast and your text is difficult to read; too much and it can be harsh or produce a “glow” effect that’s hard on the eyes. This is an important consideration in dark mode UI design best practices.

Brand Color Adjustments
Vibrant, bold color brands can be too overpowering against a dark background. You might have to adjust your color palette so that everything seems balanced and readable.

Best Practices for Dark Mode UI Design
If you’re considering adding dark mode to your site, here are some tested-and-proven tips to ensure it looks fantastic and is easy for all to use:

1. Refrain from Pure Black and Pure White
Rather than employing pure black (#000000) as background and pure white (#FFFFFF) as text, opt for dark grays and off-whites. This helps avoid eye strain and presents your site in a cleaner, more professional appearance.

2. Test your Contrast
Ensure that your text is visible over the background, but do not overdo it. Utilize online tests to verify contrast ratios and make your site available to every visitor.

3. Apply Color Sparingly
In dark mode, a bit of color is enough. Use your brand colors on buttons, links, or highlights, but use them sparingly so they do not overwhelm the design.

4. Keep it Simple
Dark mode web design benefits most when things are uncluttered. Provide room for your content to breathe, and use negative space to have your site feel open and easy to use.

5. Provide a Toggle
Make it easy for users to switch between dark mode and light mode. If it’s possible, also remember their selection for use next time. This little feature can contribute to big user happiness.

6. Test, Test, Test
What appears wonderful on your laptop during the evening may not be usable on a phone during daylight. Test your design on various devices and under various lighting conditions to ensure that it’s always legible and welcoming.

Dark vs Light Mode UX: Which is Better?
The reality is that there isn’t a single answer. Some users adore dark mode for its aesthetics and comfort, while others like the known and readability-friendly light mode. The best is to offer your users the choice and ensure that both are looking and feeling amazing.

Dark mode web design is not a trend; it’s a considerate approach to improving user experience, conserving battery life, and bringing your brand into the modern era. But as with any design decision, it has its own share of challenges. With these dark mode UI design tips and prioritizing your users’ needs, you can have a site that’s both gorgeous and functional, regardless of the mode their users employ.
