Dark Mode Design Guide: Patterns That Users Actually Prefer (2026) | Launchwork Digital
Why do 82% of users prefer dark mode? Learn the colour systems, WCAG 2.2 contrast ratios, and iOS/Android patterns that make dark themes work. Includes code examples.
Dark mode has evolved from a nice-to-have to an expected feature. But creating an effective dark theme requires more than just inverting colors.
Don't Just Invert
Simply inverting your light theme rarely works well. Dark mode requires intentional design decisions, particularly around elevation, contrast, and color saturation.
Elevation and Depth
In dark mode, lighter surfaces appear closer to the user. Use subtle gradients of gray to create depth and hierarchy, rather than relying on shadows.
Color Considerations
Reduce saturation for accent colors in dark mode. Highly saturated colors that look great on white can be jarring on dark backgrounds. Aim for softer, more muted tones.
True Black vs Dark Gray
Pure black (#000000) can create harsh contrast and cause 'smearing' on OLED screens. Consider using dark grays like #0a0a0b for a more comfortable viewing experience.
Testing is Essential
Test your dark mode in various lighting conditions and on different devices. What looks good on your high-end monitor might be illegible on a budget phone.
Dark mode, done well, can reduce eye strain, save battery on OLED screens, and provide a premium aesthetic that users love. Accessibility should be at the heart of your dark mode implementation — see our guide on building accessible websites for WCAG 2.2 compliance fundamentals.
Frequently Asked Questions About Dark Mode Design
**Is dark mode better for your eyes?** Dark mode can reduce eye strain in low-light environments by lowering screen brightness. However, in well-lit rooms, light mode with proper contrast is often easier to read. The best approach is offering both options and letting users choose based on their environment and preference.
**Should every website have a dark mode option?** Not necessarily, but it's increasingly expected. If your audience includes developers, designers, or tech-savvy users, dark mode is almost mandatory. For other audiences, it's a strong nice-to-have that signals modern design thinking. Consider your brand colours—some brands translate better to dark mode than others.
**How do you design for dark mode accessibility?** Maintain WCAG 2.2 contrast ratios (4.5:1 for body text, 3:1 for large text) in both modes. Avoid pure black (#000000) backgrounds—use dark greys like #121212 or #1a1a1a instead. Test with screen readers and ensure focus indicators remain visible. Reduce colour saturation by 10-20% for dark backgrounds.
**Does dark mode affect website SEO?** Dark mode itself doesn't directly affect SEO rankings. However, it improves user experience metrics like time on page and bounce rate, which are indirect ranking signals. A well-implemented dark mode also reduces CLS (Cumulative Layout Shift) if done correctly, which is a Core Web Vital.
**What colours work best for dark mode design?** Use desaturated versions of your brand colours—reduce saturation by 10-20% from your light mode palette. For backgrounds, dark greys (#121212 to #1e1e1e) work better than pure black. For text, off-white (#e0e0e0 to #f5f5f5) is easier on the eyes than pure white (#ffffff). Accent colours should be lighter variants of your primary palette.
