I was wondering if there is a tool that can identify all primarily used colors in a picture and show me a list or color code?
You can do this directly in Photoshop!
- Select an Image
- Open "Save For Web"
- Select "GIF Restrictive" from the dropdown labelled "Preset"
- Select how many colours to include in the top right field labelled "colours". Sixteen is probably a good starting point. Or else just try leaving it on "auto".
- Save Your colour table - Find the section labelled "Colour Table". You can see that as it literally has the extracted colours in it already, (see image). On the top right hand side of this section you will see an icon that has three horizontal lines. Click this icon and select "Save Colour Table". This will prompt you to save a .act file.
- Load Your Colour Table - Now all you have to do is load the colour table you just saved on what ever project you would like to work on. To do this, open the swatch window, then click on the icon that has three horizontal lines in the top right and click "Load Swatches".
Also Adobe Kuler has some cool functionality for doing this. Just hit the camera icon top right "Create from image". But it seems pretty limited:
