テーマ設定を管理する

You can manage how GitHub looks to you by setting a theme preference that either follows your system settings or always uses a light or dark mode.

GitHub を使用時期と使用方法を選択して柔軟性を高めるために、テーマ設定をして GitHub の外観を変更できます。 You can choose from themes that are light or dark, or you can configure GitHub to follow your system settings.

You may want to use a dark theme to reduce power consumption on certain devices, to reduce eye strain in low-light conditions, or because you prefer how the theme looks.

If you have low vision, you may benefit from a high contrast theme, with greater contrast between foreground and background elements. If you have colorblindness, you may benefit from our light and dark colorblind themes.
