I suspect the definitions of red and green were chosen carefully; red
is #ff0000 and green is #008000. There is a significant difference
between the two even if the colors appear identical (the difference
between #808080 and #404040 or something like that). This distinction
is much easier to make with a background color than with a text or
thin border color--maybe the test writers should be encouraged to use
background colors wherever possible.
