Is dark mode necessary for a corporate website?

Implementing dark mode on a corporate website is not strictly necessary unless your user data shows a clear demand for it. For many business-to-business brands, the majority of traffic occurs during standard working hours on desktop devices where light themes are preferred. Creating a dark theme requires significant design system resources to maintain color contrast and brand consistency. If your team does not have the capacity to test and update two separate themes, it is better to focus on a single, highly polished light theme. A poorly implemented dark theme can damage your brand reputation and create accessibility issues. Therefore, you should only proceed if your analytics and brand guidelines support the long-term maintenance. Ultimately, user experience should guide this decision rather than design trends.
