Ember for Mac lets you upload your library to iCloud, sort by color

Realmac has updated Ember with a couple of major features. Ember can now store your library in iCloud, allowing you to keep one photo library between multiple Macs. Realmac cautions that the initial upload to iCloud may take some time depending on the size of your library. Ember can also now analyze your images and sort them by color. You can search through colors, and even create smart collections based on colors. The update can be downloaded right now from the Mac App Store.
