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. -- John
