If you're frustrated with the tiny size of the color ramp area in Photoshop's built-in Color panel (as seen in the screenshot at the right), you'll find some much-welcomed relief in Anastasiy's (a talented Adobe developer) new SWF panel, available for download here.

The Color Picker from Anastasiy (available for Adobe Photoshop CS4 only) adds a new, much more useful color picker, at a much larger size (as seen below).

You can get the same thing in Photoshop without this new tool, but it requires a trip to a dialog box. By using this Color Picker, the tool is available from a regular panel via a click of the icon.

To install the new Color Picker, expand the zip file and drop the resulting colorpicker folder into your Adobe Photoshop CS4/plug-Ins/Panels directory. To activate the Color Picker, go to your Photoshop menubar and select Window>Extensions>Color Picker.
