Color Pickin Chooser Pro..

All available from a handy context (right-click) menu.

Import images (even whole folder or drives!) as easily as a drag & drop.

Automatic menu sorting - throw in folders of images, they become menu sections.

Select any folder to use as picker images.

Comes with a selection of sample pickers.

And more!

The smoothest gradient selector on planet earth, well, pretty smooth.

With live luminance facility (F5)

You can also create gradients from two picked colors.

Ctrl+Click sets the top of the gradient. Ctrl+Shift+Click sets the bottom. Yum!
You can create some truly spectacular or spectacularly ugly gradients this way!

With live mag facility (F6)

Includes "super-mag" for out-of-gui pixel capture anywhere on your desktop(s).

Magnification levels from 1x (1:1 capture) all the way up to 50x (a single pixel sample!)

(or whatever output format you specify)

Hold down SHIFT to see live color values in your chosen output format, with or without prefix, as required.

You can save colors in any number of color groups.

Keep all your color schemes in one handy central location.

Groups can be created, copied, edited and deleted, colors created, renamed, and deleted, all from within the gui.

You can sort the colors in your group by name, by Red, Green or Blue values, or by Hue, Saturation, or Lightness values.

Repeat the sort to sort in reverse!

Unpatented 'Duplex Fuzzy-Algo Multi-Sort™' functionality enables you to mix-and-match your sort routines to get the color order exacitaly right! No really, try it!

Handy HotKey controls for all sort functions make sorting quick and easy.

Easy export/backup and restore (drag & drop) of color groups.

Drag & drop to share color groups with other users.

Drag & drop ini files to suck colors from other program's preferences, even whole folders of files (non-ini's are ignored)

Automatic "merge" functionality, so you can distribute color group files that other users can simply drag in.

Export colors as cpc color groups or color palettes.

Drag and drop palette files onto Color Pickin Chooser to suck out all their colors.

Retain original GIMP palette and color names, even comments.

Color Pickin Chooser doubles as a capable palette converter.

Color group and Gimp palette comments are retained during all import and export functions.

Attach comments and notes to your color groups, view and edit them, all from within Color Pickin Chooser.

Everything dynamically updates everything else!

Copy and auto-copy hex color values to the clipboard..

Rapid color picking in multiple output formats..

Autoit RGB
Autoit BGR
Visual C++
Delphi
RGB Integer
RGB Float
HSL (Hue/Saturation/Lightness)

EVERYTHING has a HotKey, well, almost. There's also a global HotKey so you can summon Color Pickin Chooser whenever you need it (Ctrl+F1 by default).

Click the picker to pick a color, long-click to capture an area. I got the idea from using Android!

As a bonus, we get the system picker to remember its custom colors! Now there's a first!
