However, Elements is a relatively large program, and I don't always have it running. Also, after picking a color, you also have to then select and copy the RGB value if you wish to use it. So I went looking for a third-party (freeware) RGB color selector that was faster to load and use. After looking at about 15 of them, I found one that really works perfectly for me -- ColorTagGen. This simple little app displays the standard Apple color selector, as well as its own dialog box. Choose a color in the selector, and you get an instant display of its RGB value, as well as the hex-encoded RGB value. There's also a very handy Copy HTML button, which puts the hex-encoded value on your clipboard, saving some mouse and keyboard work.
A simple little program, and there are probably another 25 like it that I didn't find in my brief search ... but ColorTagGen seems to be perfect for my occasional needs outside of Photoshop Elements.
