It seems like there's an app for almost everything these days, and one very useful new addition to the arsenal is House Beautiful's 500+ Favorite Paint Colors, which makes the task of narrowing down swatches in a deck much easier with helpful images and advice.
The magazine has put together a comprehensive tool that gives information on 669 paint colors from the top quality paint manufacturers. You can choose a color to learn what other designers have done with it in the past for inspiration. Or you can fill your iPad screen with the color to use as a large paint chip.
For these and other functions, you can purchase the app for just $4.99 from the iTunes App Store.
