hey!...I just went looking for a 'color selector' and found this little beauty!

It will allow you to determine the RGB of any color you see, OR to move the sliders around till you find a color you like!...and lots more... what fun...post in colors no one else uses..*grin*
if you want it, and want to avoid the 6 step download from sourceforge. here is the download link
