passport puzzle

A few weeks ago, with the help of a very nice postal employee, I bagan the process of renewing my passport.  It came in the mail today and it looks very nice, new and crispy clean with all those blank pages.  I guess those will be a challenge to me.  I love to see those pages being stamped.  If I had lived in the good old days I would have had one of those suitcases with the travel stickers pasted all over it.  What surprised me about this passport is that, after all the jokes you hear about terrible passport pictures, mine doesn't look too bad. If you overlook the lack of glasses and a smile, it sort of looks like me but, because of the lighting or something when my picture was taken, I look like I have strawberry blonde hair.  This is not a bad look, in fact it's the look I had for many years, but for the last several years (10 at least) my hair has been gray.  So here's the question. Do I dye my hair to match my passport or just hope security people will assume I had a very rough flight?
