When it comes time to touch up walls that have been marked or scratched, trying to find the correct paint can on the storage shelf is a huge headache. Even if you do manage to find the correct color for a room, the can may so old and rusted that the paint inside is useless.
To make shopping for new cans of my existing paint colors easier, I started taking pictures of the labels and uploading them to the cloud, so I can find them later. Then I bring the photo with me to the store, and the associate can whip up a can of the same color using the ID on the label. — JD Williams
The same concept works for things such as flooring, tile, etc. Taking photos of the labels and storing them in a folder on your computer or in the cloud makes it easy to order additional or replacement pieces for your home. It’s your own wall paint colors catalog.
