Not a serious question...
You are motor sailing SW down the north Brittany coast about 15 miles offshore in good visibility, it is 11pm.
There is another craft in sight to the west, it is a yacht about 1 mile distant approaching on a reciprocal course. You expect to pass green to green by about 300 yards.
As you watch the other yacht you notice that it occasionally shows green over white over green and then reverts to white over green.
What do you make of this?
