There are two types of field color overlay attributes:
Transparent
Opaque
Field placement in the packet is an important consideration when using
field color attributes. If a line field is defined before the overlay (text or
constant text) field, the line field is blocked out by the overlay field,
depending on the overlay field's color attribute. If a line field is defined
after the overlay field, the line field is not blocked out by the overlay field,
regardless of the overlay field's color attribute.
