With the New Registration Form released in Dec 2016, you can do more design than before to fit your event and organisation.
1. Go to "Details" under Event.
2. Scroll to the bottom for "Event Page Theme Color".
3. Select colors for the form or simply type in a color code.
The font color shown in the color pickers also represent the actual font color on the form.
4. Check this box if you prefer the old layout of Registration Form.
