Trying to get Hex/RGB value of a color preview swatch, please help!

Hi everyone   In configuration page some colors are customizable.  When clicked on any of the input fields, a color chooser pops up. Selecting a color populates the field with the hex value...

    backgroundColor is not a method, it's the actual property.   So, just compare that property to the desired value.

Hi Robert,

 

As you suggested, I am using IE 11. Now I am getting runtime error:

 

            JavaScript runtime error.
      TypeError: Cannot read property 'color' of null
 
If you take a look at the above screenshot, the style (color) in named 'backgroud-color'. I am using the following to Log the color:
var style = page.contentDocument.defaultView.getComputedStyle(colorPrimary, "");
Log.Message(style.background-color);
I am not quite sure if I should be using 
Log.Message(style.background-color);
or
Log.Message(style.color);
 
Either way, I am getting the same error. 
 
Thank you.

In the code that I'm using, I get the element from the page in IE... then I get the "currentStyle.backgroundColor" property.  I think that's better than the getComputedStyle method.  See if that works better for you.
