Note Friendly is a Chrome add-on developed by Kazuhiro that allows users to change the background colors of the Note application. By changing the background color from pure white to gray, it provides a more eye-friendly reading experience, even when reading articles for long periods of time. The gray background is designed to maintain optimal contrast ratio, ensuring readability even for those with color vision issues.

Furthermore, Note Friendly also supports dark mode. When the operating system's appearance mode is set to dark, the background becomes black and the text becomes white. This enables comfortable reading even in dark environments.
