How does eclipse change the color of the entire page?

To change the overall page color of the Eclipse editor, you can follow these steps:

1. Open the Eclipse editor.
2. Select “Window” in the menu bar, then choose “Preferences.”
3. Expand the “General” section in the pop-up dialog box and select “Appearance.”
4. Choose “Colors and Fonts” in the panel on the right side.
5. Under the “Basic” tab, you can change the background color of the editor. Select “Text Editor” and click on the color picker icon next to “Background color”.
6. In the color selector, choose the background color you want and then click “OK” to confirm.
7. Click on the “Apply” button to apply the changes and close the preferences dialog box.

In this way, you can change the entire page color of the Eclipse editor. Please note that this setting will only affect the appearance of the Eclipse editor, and will not change other parts such as the menu bar or toolbar color.
