Color Collect is a free, simple, and fun app for iPhone. It lets you take photos or videos and pick colors from them. It can be used for your photos, for instance, to make them more colorful. The best part is that it doesn't require a lot of processing power, so it works on older devices.

It's really easy to use. You can simply tap the camera icon to take a picture, and you can then choose a color from the palette that appears on the screen. It works with both photos and videos.

When you save your color palettes, you can use them to edit your photos in a variety of ways.
