Google's Theme Creator extension for Google Chrome allows you to easily build and export your own themes from a simple graphical interface. Instructions in this article apply to the desktop version of Google Chrome for all operating systems. How to Make Your Own Google Chrome Themes To customize Chrome with the Chrome Theme Creator tool: Go to the Chrome Theme Creator page and select Add to Chrome. Select Add app to install the Theme Creator. Chrome will automatically open the apps tab. Select Theme Creator. Give your new theme a name in the field at the top-left of the page. Select Upload an image and choose a high-resolution image to base your theme around. Unsplash is a website where you can find tons of great images completely free of charge. Vector patterns tend to work best. After you upload the image, you'll see a preview on the right side of your screen. Use the controls below the image to adjust your background image. Select Generate Colors to create a color scheme for your theme based on the image you just uploaded. The website will automatically update your preview to show you the colors it detected from the image you uploaded. If you'd like to alter any of the colors, select the Colors tab. Under this tab, you can select any of the colors for your browser window and change them as you like. Switch back to the Basic tab and select Pack and Install to package your new theme as an extension for Chrome. You'll receive a warning from Chrome letting you know malicious extensions can harm your computer. Select Keep to download your theme. Go to chrome://extensions/ in the Chrome browser and select the Developer Mode toggle switch in the top-right corner to enable it. Locate the CRX file you just downloaded on your computer, then drag-and-drop it into the browser window. Select Add theme in the pop-up window. If you see a "cannot decode image" error message, try using a different image for your custom theme. Chrome will take a few seconds to apply your theme. If you want to revert back to the default, select Undo.
