I want a good app to index what would mostly be colour palette inspiration, but via a range of images, without having to document the colour palette myself. Dribbble and Designspiration generate one, so that functionality basically.
Spectrum allows you to create a color palette from an image then tweak it. It's a pain in the ass if you're creating these for print work (CMYK or Pantone) but it's a great place to start for inspiration or if you're designing web or UI work.
There are a variety of apps in the AppStore which will generate a colour palette. For instance, ColorSchemer
This isn't quite what I'm after, perhaps I'm not explaining correctly....
Beneath his image is a summary colour palette of the image: http://designspiration.net/image/395911124503/
The colour palette is also generated from Dribbble shots: https://dribbble.com/shots/3032100-Octopus-data-circuit-board-logo-design
I'd love a desktop (Mac) app that I can save images into folders and have it generate colour palettes as these sites do.
Once upon a timer there was a nice app called Ember, wich is good for this purpose. You can search for colours, but not like dribbble with the colour palette on the side. Sadly it seems to be discontinued in development.
Alternatively to Ember there is Pixave 2, but I'm not sure if it supports colour palettes. But at least it seems to be a nice offline image saving app!
Pixave has what I'd call partial color support. It generates a simple palette from images in the library but doesn't do nearly as good a job as Dribbble. It does have a nice feature that lets you search your library for colors though. You choose whether you are looking for the focus, primary, secondary or other color and then click on a swatch to find matches.
