Windows 10 doesn’t have any options for you to customize folder colors. However, there are a few software packages that you can alter folder colors with. Not all of them are freeware, but Colorizer is one that is. This is a package with which you can select new folder colors from the context menu.
Open the Colorizer page on Softpedia to add it to Windows 10. Click the Download Now button to save the software’s setup wizard. Then click FolderColorizerSetup to install Colorizer.
Now right-click the Windows 10 desktop and select New > Desktop to add a new folder to it. Next, you should right-click the folder on the desktop to open its context menu that will now include a Colorize option as in the snapshot below. Select that option to expand its submenu.
The submenu above includes a few colors for you to select. Choose a color from there to add it the folder as below. Press the Restore original color option on the context menu to revert back to the default color.
You can add new colors to almost any folder in File Explorer much the same. Note that there are a few folders you can’t apply colors to. For example, you can’t add new colors to compressed Zip folders in File Explorer.
Select Colors on the submenu to open the window below. That includes a circular palette with which you can select custom colors by dragging cursor over it. You can also drag the color bar below to choose further color varieties. You should press the + Add color button to add the new color to the context menu.
Colorizer is a decent freeware package to customize folder colors in Windows 10, 8 and 7 with. You can also customize the folder colors with alternative programs such as FolderMarker and Folderico, but they are not freeware.
