1.  Copy Color as Hex Value

At the final stage of materializing a Photoshop design into html/css, often colors need to be copied as Hexadecimal format (i.e. #00cc00 for green).  Use the Eyedropper tool (shortcut key I), right click at the pixel, and choose “Copy Color’s Hex Code”, then paste it in your html text editor.  “Copy Color as HTML” would produce code like color=”#00cc00″, which is not as useful in most scenarios.
