Catch the Color

/*
 Game -Catch The Color 
  
  IDEA: A reaction timer based game which requires the immediate ttention of player to catch the color 
  LOGIC: This sketch first prints introductorty statements if the game .
  Then the colour to be found is printed and game begins!
  If the color is found you win else you loose ...
