how do you change the colour of the little title boxes in your profile?

try this :

<style>

}
/* change all headings on page to different colors. */
  .profile .contact .heading,
  .profile .table-section .heading{
   background-color: purple;
   color: rgb(255, 77, 166);
}

you can change the rgb to change the colours
