Why does the field go white when part of question is answered or a required question is not answered?

I can't read the white writing if the field is highlighted white.  I can't work out how to change the font colour.  Is there another way I can overcome this problem?

Please try inserting this custom CSS code to make the background color of the highlighted fields transparent:

.form-line-active {
background-color: transparent !important;
}

.form-line-error {
background-color: transparent !important;
}

Here's a guide on how to inject custom CSS. Hope that helps. Thank you.
