Maybe they are highlighting the blue in the flag for a reason. Look at what Blue means in the flag: "The colors of the pales (the vertical stripes) are those used in the flag of the United States of America; White signifies purity and innocence, Red, hardiness & valour, and Blue, the color of the Chief (the broad band above the stripes) signifies vigilance, perseverance & justice." Definition of vigilance: the action or state of keeping careful watch for possible danger or difficulties.
