+## Description
+
+I want to set the document's background color to white and the editor's background color to gray in the [RichTextEditor](https://docs.telerik.com/devtools/winforms/controls/richtexteditor/overview) component of UI for WinForms.
+
+This knowledge base article also answers the following questions:
+- How to customize the background color of RichTextEditor pages?
+- How to set different colors for the RichTextEditor editor and document?
+- How to use PageBackColor and BackColor properties in UI for WinForms RichTextEditor?
+
+## Solution
+
+To set the desired background colors for the document and editor:
+
+1. Use the `RichTextBoxElement.BackColor` property to assign a color to the editor background.
+2. Use the `RadRichTextEditor.PageBackColor` property to assign a color to the document's background.
+
+Example code:
+
+```csharp
+// Set editor background to gray
+this.radRichTextEditor1.RichTextBoxElement.BackColor = Color.LightGray;
+
+// Set document background to white
+this.radRichTextEditor1.PageBackColor = Color.White;
+```
