The tool comes in a zip file; you just need to download ... You can also add your own custom colors in Folder Painter and customize the Icon folder with your custom color icons.

Tap the ZIP file. A moment later, an unzipped folder with the same name will appear ... If it's an image, you can even open it and tap the share icon to save it to your device's camera roll.

Once you've found or selected the file or folder, tap the three-dot menu icon next to it and select Compress. Enter the name for the zip file. Make sure your zip file name doesn't include spaces ...
