Red

Ever noticed how the color red is used in telling stories?  Schindler's list was a black and white movie with one exception, the red coat of the little Jewish girl.  It depicted the fate of that young life and brought audience to tears.

But red is used for other strong emotions.  From sultry and sexy, like ladies in red dress in so many movies, to anger and rage, to warning and danger.  Red makes the audience pay attention.  It highlights something particular and special.

Just remembering one of the classic uses of red is in a comedy bullfight.  The red cape is said to anger a bull.  Of course when Bugs Bunny entered the ring it meant war with the bull.  The red cape hid things like a shotgun and an anvil, all to the determent of the bull. Perhaps it should have been called "Bull caper by Bunny".

There is a certain amount of people that need to know what color things are.  Color sets moods and emotion.  Just imagine a sharp looking crooner in a black tuxedo and next to him is his date in a slender white backless dress and white fluffy fur around her shoulders.  Now compare that to a young guy wearing blue cutoff jeans and a tan.  His date is a curvy brunette in a red tight bikini.  Notice the glamor in the first example and the casual and sexy in the second?  Color makes a difference, and red is easily understood by most everybody.
 Red shirt makes one look spiffy, red roses to please the lady, blush red after blundering over words, and a red hand imprint on the face after insulting the object of desire (not to mention a red broken heart).
