You can change colors of buttons in your Pre-Quiz, Post-Quiz, and Webinar pages. The procedure for changing button colors is the same for all of these various page types.
Click the component where the button you want to edit is located, then open it for editing by clicking either the Edit button that appears on the bottom of the component or the Builder tab on the top left.
When the Builder opens, look for the button on the page, then select it.
Click the Properties tab of the Builder, then scroll down to the Background Color section, where the current button color and its RGB code are displayed.
To change the background color, either enter the new background color’s RGB or Hex code on the box, or click the button where the current background color is displayed, then select the new color from the palette.
