It didn't work.
This is what I changed
#popupShippingEstimator, #popupSearchHelp, #popupAdditionalImage, #popupImage, #popupCVVHelp, #popupCouponHelp, #popupAtrribsQuantityPricesHelp, #infoShoppingCart {
font-color: #000080;
}
.information {padding: 10px 3px; line-height: 150%;}

#shoppingcartBody #shippingEstimatorContent {
clear: both;
font-color: #000080;
}
But still the content is in black.
