As reported last month, Microsoft has finally started to rollout OneNote dark mode to Office Insiders. It was first spotted in a Reddit thread by Windows Central folks but has now been officially confirmed by Mike Tholfsen, Product Manager at Microsoft. It is a gradual rollout which means it will take some time before it becomes available for everyone.
OneNote's dark mode is said to transform the app's complete interface to a darker shade. It is up to the user when they want to use the app with or without dark mode. The good thing is that there is also an option which will make it adjust the theme according to the system-wide Windows theme. This is a handy feature for those who want to have both the app and the system theme to be the same.
The only slight issue is that once OneNote dark mode is enabled, it makes everything go darker including the pen colors. Some of the colors go so dark that they become illegible. This is certainly a matter of concern for anyone who loves using the application. One Reddit user mentioned the same situation where pen colors of all of his notes went darker and he had to change each one of them manually to make them legible.
As mentioned in the beginning, OneNote dark mode is currently available only for Insiders. If you not a part of the Insider program, you will have to wait until Microsoft starts rolling it out for everyone. It should take some time but we will keep you in the loop.
