How Outlook for Mac Handles Dark Mode
Outlook for Mac automatically adjusts email colors in dark mode. This helps Microsoft meet accessibility standards for darkness and contrast.
These changes happen automatically. They apply even if you use custom dark mode styles.
What Happens Without Custom Dark Mode Styles
If you do not use dark mode editing, Outlook for Mac changes your light mode colors automatically.
This can cause large visual changes, including:
White backgrounds becoming dark gray or black
Light button colors becoming muted
Reduced contrast between elements
How Custom Dark Mode Styles Behave
If you use dark mode editing, Outlook for Mac can still modify your colors.
This happens when your selected colors:
Are too bright
Do not provide enough contrast with text
Outlook for Mac evaluates both background colors and text readability.
Recommended Color Choices
Use darker colors in your dark mode color kit. This reduces the chance of Outlook modifying your design.
Avoid these color choices:
Bright colors
Bright button backgrounds
White backgrounds
Light button styles
