Summary:
Previously in colorclasses.edc border_frame dialog_base along with other base elements were defined to the default font color "White". This means if you change the default font color there are many unrelated side effects.
To fix this issue i have added a new Color define in colorclasses.edc to be used with window related items as opposed to text related items.
