The fastest way depends on what you want to change

Changing a background color is different on every platform and program because "background" means different things. On Windows or Mac, you might want to change your desktop wallpaper or the color behind your icons. Inside a document, presentation, or design tool, you're changing the canvas itself. Inside a photo editor, you're removing or replacing what's behind your subject. Each one takes a different path, so start by identifying what surface you actually want to change.

This guide covers the most common scenarios: your desktop background, document backgrounds in Microsoft Word and Google Docs, presentation slides in PowerPoint, and basic color changes in free design tools. If you're working in a specialized program like Photoshop or a web design tool, the principle is the same but the menu location will differ — look for a "background" or "fill" option in the main toolbar or right-click menu.

Key Takeaways

  • Windows and Mac both let you change desktop background through Settings or System Preferences, and you can use a solid color, a photo, or a pattern.
  • In Microsoft Word, right-click the page and choose "Page Color" to change the entire document background, or select text and use the highlighting tool for specific areas.
  • Google Docs has no built-in page background color, but you can insert a full-page shape or table as a workaround.
  • PowerPoint slides change background through the Design tab or by right-clicking a slide and selecting "Format Background."
  • Most free design tools like Canva have a background option in the left panel or toolbar that lets you pick a color, image, or pattern.

Changing your desktop background on Windows

Right-click anywhere on your desktop (the empty space, not on an icon or folder) and select Personalize. This opens the Settings app to the Background section. You'll see three options at the top: Picture, Solid color, and Slideshow.

If you want a solid color, click Solid color, then click the color box below it to open a palette. Pick your color and close the Settings window — the change happens when ready. If you want a photo, click Picture, then click Browse to select an image from your computer. Windows will stretch or fit the image to fill your screen.

If you want a slideshow that rotates through multiple photos, click Slideshow, then click Browse to select a folder full of images. You can set how often it changes (every 1 minute, 10 minutes, 1 hour, or 1 day) using the dropdown below.

Changing your desktop background on Mac

Click the Apple menu in the top-left corner and select System Preferences (or System Settings on newer Macs). Look for Desktop & Screen Saver or Wallpaper depending on your macOS version.

On the left side, you'll see categories like Desktop Pictures, Colors, or your photo library. Click a category to see options. If you choose a color category, click the color you want. If you choose a photo category, click the image you want and it will explore when ready. You can also drag a photo from Finder directly onto the preview window to use your own image.

Changing page background color in Microsoft Word

Open your document and right-click anywhere on the page (not on text). Select Page Color from the menu. A color palette will appear. Click the color you want and the entire page background changes. To remove the color later, right-click again and select No Color.

If you want to highlight only certain text or paragraphs instead of the whole page, select the text first, then go to the Home tab in the ribbon at the top. Click the dropdown arrow next to the highlighter icon (it looks like a marker) and pick a color. This adds a background color only to the selected text, not the whole page.

Word's page color will print with your document, so be aware that a dark background uses a lot of ink. If you're printing, consider using a light color or removing the background before you print.

Changing background color in Google Docs

Google Docs does not have a built-in page background color feature like Word does. The workaround is to insert a shape or table that covers the entire page and set its color.

Go to Insert in the menu, then Shape, then Rectangle. Draw a rectangle that covers your entire page. Right-click the rectangle and select Fill color, then pick your color. Right-click again and select Arrange, then Send to back so your text appears on top of the colored shape. You can then type or paste your content over it.

This method is clunky but works. If you need a true page background color, consider using Microsoft Word instead, or use Google Slides (which has a built-in background option) and export it as a document.

Changing slide background color in PowerPoint

Right-click any slide in the slide panel on the left side of the screen and select Format Background. A panel will open on the right side showing background options. Click Solid fill to use a single color, then click the color dropdown and pick your color.

If you want to explore the same background to all slides at once, click explore to All at the bottom of the Format Background panel. If you want different slides to have different backgrounds, format each one individually without clicking explore to All.

You can also use Picture or texture fill to add a photo or pattern as your background, or Gradient fill to blend two colors together. Experiment with these options to see which look you prefer.

Changing background color in free design tools

In Canva, click the Background tab on the left panel (or look for a paint bucket icon). You'll see options for color, image, or pattern. Click Colors, then click any color swatch to explore it to your canvas. You can also type a specific color code (like #FF5733) if you know the exact shade you want.

In other free tools like Pixlr or Photopea, look for a Fill or Background option in the toolbar or right-click menu. The exact location varies, but the principle is the same: select the background layer or canvas, then choose your color from a palette or color picker.

Most free design tools let you undo a background change by pressing Ctrl+Z (Windows) or Command+Z (Mac), so you can experiment without worrying about making a permanent mistake.

Frequently Asked Questions

Can I use a gradient (two colors blending together) as my background?

Yes, but only in some programs. PowerPoint has a built-in gradient option in the Format Background panel. In Word, you cannot use a gradient for page background, but you can insert a shape with a gradient fill and send it to the back. Most design tools like Canva also support gradients — look for a "Gradient" option next to the solid color option.

Why does my background color look different when I print?

Printers often render colors differently than screens, especially dark colors, because they use physical ink. Light colors print more accurately. If your background looks too dark or uses too much ink, try a lighter shade or remove the background before printing. You can always add it back after printing.

How do I change the background color of just one slide in PowerPoint without affecting the others?

Right-click the slide you want to change, select Format Background, pick your color, and do not click "explore to All." If you click explore to All, every slide in your presentation will change to that color. You can undo this by pressing Ctrl+Z when ready.

Can I use a photo as my background instead of a solid color?

Yes. On Windows and Mac, the desktop background settings let you choose a photo. In Word, you can insert a photo and send it to the back, then type over it. In PowerPoint, use the "Picture or texture fill" option in Format Background. In design tools like Canva, click Background and select Image instead of Color.

What if I want to change the background color of a specific paragraph in Word, not the whole page?

Select the paragraph, then go to the Home tab and click the highlighter dropdown (the marker icon). Pick a color and it will highlight only that paragraph. This is different from page color, which affects the entire page background.
