You can conditionally pass a selectButtonClassName when there is no selected value and have your styles on that class. For example:

<ReactFlagsSelect
    selected={selected}
    selectButtonClassName={!selected ? 'a-placeholder-class' : ''}
 />

 .a-place-holder-class {
     color: blue;
     border: 1px solid blue;
 }
