    Hi, is it possible to pick a color from a picture, instead from a palette. Or pick a color from anywhere in the browser. Thanks, Henry

    In the current release of RadColorPicker,  you can get and set the current color of a RadColorPicker programmatically only through a System.Drawing.Color type.

    But, it is also possible to convert a hex color code to and from a System.Drawing.Color through the static methods FromHtml and ToHtml of the System.Drawing.ColorTranslator class.

    There is no functionality in RadColorPicker to get the hex value of the selected pixel of an image or in the screen display. It seems that this could be possible using JavaScript. See the JavaScript eyedropper (tell color of Pixel under mouse cursor).

    If you could do this with JavaScript, you'd then be able to use the value to set the "SelectedColor" by passing it to this method:

    RadColorPicker1.SelectedColor = ColorTranslator.FromHtml(hexValue);

    Hope this helps!
