Change Colors in Free Version

Hi,

In the Free version, you can change the legend colors with some CSS code.

.wpbs-container .wpbs-legend-item-icon-1 div { /* available */
    background-color: green !important; 
}

.wpbs-container .wpbs-legend-item-icon-2 div { /* booked*/
    background-color: red !important; 
}

You can add custom CSS code in WP Admin -> Appearance -> Customize -> Additional CSS
