Hi Info165,

To change the color and the font-size paste below CSS code in your child theme CSS. Also if you want more features like font-family, font-size and font-color, color skin you can upgrade it to pro version of the Interface theme and change as you wish.

.info-bar,
.info-bar .info ul li a {
    color: #fff;
    font-size: 14px;
}

Thank you!
