Conclusions

The question of choosing an interface theme – dark or light – is strategically important and requires a comprehensive approach. It is necessary to consider many factors:

– User comfort and health: Eye strain and the psychology of perception directly affect users’ comfort and health.

– Type of content and target audience: Businesses need to base their choice between light and dark themes on the content and audience. Light themes are more suitable for text content, while dark themes are better for visual and professional tools.

– Technical aspects and performance: CSS patterns and their impact on power consumption are important, especially for mobile devices.

– Risks and accessibility: Dark themes can create barriers for users with visual impairments, which can affect reputation and productivity.

The choice of theme should be a considered decision based on analytics, A/B testing and a strategic UX audit.
