Earlier this year I mentioned a handy UIColor helper library that includes hundreds of pre-defined custom colors, and a number of color schemes that make it a great help for choosing a color palette for an app.
Here’s a handy tool from Adobe called Kuler that you can use to easily create color palettes.
With Kuler you can create a palette using live video, a picture taken with the camera or an existing image in the device photo library, your Google Photos or Flickr.
The colors are automatically chosen using an algorithm but you can change the chosen colors by dragging to different areas of the image or using a color wheel.
Here are a couple of images from the App Store listing showing Kuler in action:
You can find Kuler on the App Store here.
Definitely the definitive iOS app for creating palettes. Thanks to Tom for the tip about this app.
