The background-color there is set to blackish.
]]>If not, these are the two classes you want to change:
.woocommerce-tabs > .tabs .active a
.woocommerce-checkout-nav .is-active a
You could just add them to your style.css like with your own color and it should work
.woocommerce-tabs > .tabs .active a {background-color: #FF0000!important}
.woocommerce-checkout-nav .is-active a {background-color: #FF0000!important}

.woocommerce div.product .woocommerce-tabs ul.tabs .active a {color: #000!important}
What browser do you use?
