<p dir="auto">It  seems like Terminal Preview does something weird with color 7...  mapping it (I think) to the 'foreground' color in the scheme.  This is  confusing, because the default scheme (Campbell) has a different color  for 'foreground' than color 7.e.g., run "color  7f" and "color f7" commands in Terminal  Preview.  In both cases, the text color is lighter than the  background... but that shouldn't be possible.</p>
