Michael,

Here is a function that I use to lighten a color.  You could modify this to get a darker color as well.  Hope it helps.

function lightenColor origColor
  try
    repeat with i = 1 to 3
      add 50 to item i of origColor
      if item i of origColor > 255 then put 255 into item i of origColor
      if item i of origColor < 0 then put 0 into item i of origColor
    end repeat
    return origColor
  catch tSomeErr
    return origColor
  end try
end lightenColor
