At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
I'm not sure what you're looking form, but it seems like you are trying to allow your users to pick a color in a radio button, if so, then I think this will not be possible since the Form Builder will not allow you to add this HTML code, for example, I assume that you are trying to add a field similar to the one shown in this link: http://www.w3schools.com/html/tryit.asp?filename=tryhtml_input_color
But if you're looking for something else, please do let us know and we will be glad to help you.
