Hi Vinod,
Thanks for the feedback! Once I see that more people are getting some use out of the script, I'll work on the enhancements.
The functionality that you suggested for a tool that attempts to automatically reproduce the look of another application is interesting. Such things are certainly beyond the scope and abilities of Adobe's Extendscript, however it would certainly be possible to write a Win32 application that could do some version of your idea. As far as it being fully automatic, I'm not sure how you'd easily identify which parts of another application would translate to the interface element groupings that I've implemented (beyond the window frame). Something that might be more feasible, yet equally valuable/convenient, would be to allow the user to simply point to a place on the screen and pick up the color similar to the eye dropper tool in Photoshop. This would still require writing a companion tool and facilitating communication between the script and tool, but I could see it happening.
In the meantime, short of taking a snapshot of the screen and pasting it into an application like Photoshop to determine the colors of an existing application, there are many tools out there that try to make it easy to determine the color of any pixel on your screen. Do a search for color capture utilities. Here's a free example: http://www.greeneclipse.com/eclipsepalette.html
Take care, Corey
