Hi, I am trying to do a similar thing here.....I have changed the label colour but for some reason the radio button text is still appearing in black? I tried the html code above and it doesn't seem to be making a difference.
The only slight issue, is that it changes the color for all the values... the "Select Industry..." default text as well as all the values you can select from the list.
If anyone knows of a way to change only the color of "Select Industry..." and not the values in the list, I would love to know how! I'd like to change the default 'select' text to grey, but leave all the values as black.
