ArcGIS Pro supports two visual modes of operation:
- High contrast mode, which is a Windows operating system setting
- Light or dark theme, which is an ArcGIS Pro application option
High contrast mode
The readability of the ArcGIS Pro user interface can be improved by turning on high contrast mode. The system color scheme increases the color contrast of text, menus, tabs, and icons to make them more distinct and easier to identify for users with low vision or color blindness. However, high contrast mode does not change the appearance of certain views in ArcGIS Pro, such as maps and charts.
You should close any open ArcGIS Pro sessions before you turn on high contrast mode. Restart ArcGIS Pro after high contrast mode has been turned on.
To turn on high contrast mode, press left Shift+left Alt+PrtScn on your keyboard and click Yes on the High Contrast prompt.
To turn off high-contrast mode, use the same keyboard shortcut: left Shift+left Alt+PrtScn.
For other ways to turn on high contrast mode, see Use high contrast mode on the Microsoft Support site.
The light and dark theme settings are ArcGIS Pro application options. They are aesthetic choices for the user interface, not accessibility settings. However, you may find that one theme or the other improves visibility or reduces eyestrain under some conditions.
Follow these steps to change the application theme:
- Open the ArcGIS Pro Settings page.
- On the start page, click Settings in the lower left corner.
- From an open project, click the Project tab on the ribbon.
- In the list of tabs on the left, click Options.
- On the Options dialog box, under Application, click General.
- On the right, expand Application Theme. Click the drop-down arrow and click Light or Dark. Click OK.
- Restart ArcGIS Pro.
If high contrast mode is turned on, only the light theme is supported.
