Change color of highlited form

When clients are filling out a form it high-lites a color when they click on it.  This gets distracting.  We want to change this color to clear.  So when the client clicks on the box to fill it out there is not another color overlaying it.  See our example below the pale green color around the form box when we select it....where do we change this color to clear or none?  See our example attached.

Hi,

You can simply go to 'Designer', under 'Color Scheme' there are two options that allow you to change the highlight color.

To change the highlight color select 'Simulate highlight' checkbox, click the gear icon on the right then click the dropdown to choose a color. You can make it transparent using the slider. 

Please let us know if you need further assistance!
