Hello there,
Thank you for reaching out to us here.
Could you please try to apply the following CSS code through the Simple Custom CSS plugin or child theme’s style.css?
.widget_sydney_services_type_a .roll-button{
background-color: #1c7cf4;
border-color: #1c7cf4;
}
.widget_sydney_services_type_a .roll-button:hover{
color: #1c7cf4;
background-color: transparent;
}
Adjust the hex color code as it might not the exact blue that you want.
Regards,
Kharis
