Morse Code Flag for the Number Six: 6 = _ . . . .

Since stars represents dots and stripes represent dashes, we have the number 6 Morse Code flag with one stripe and four stars underneath.  The background colour indigo, or dark blue and sometimes blue, is associated with the 6th colour of the visible spectrum.

Morse Code Flag for Five: 5 = . . . . .

Since Morse Code for five has five dots, we have five stars on the flag.  There are no stripes because there are no dashes coded in the number 5.  As blue, or sky-blue, is the 5th color of the visible spectrum, the field is blue.  The stars are red because the contrast indicator for blue is red.

Morse Code Flag for Four: 4 = . . . . _

The Morse Code Flag for the number 4 has a green background since green is the 4th colour of the rainbow.  The four stars represent the four dots, while the one stripe represents the one dash.

Morse Code Flag for Three: 3 = . . . _ _

The Morse Code Flag for the number 3 has a yellow background, because yellow is the 3rd colour of the visible spectrum.  The three stars represent the three dots while the two stripes represent the dashes.


Coincidentally the pattern of stars and stripes mirrors the flag of Washington DC. The primary difference is that the DC flag has a white background and red stars and stripes.  Funny tertiary coincidence is that DC is the also the 3rd official capitol of USA, under the US Constitution.

Morse Code Flag for Two: 2 = . . _ _ _

The Morse Code Flag for the number 2 has two stars for the dots and three stripes for the dashes.  Since orange is the second colour in the prism, it is its appropriate background.

Morse Code Flag for One: 1 = . _ _ _ _

The Morse Code Flag for One has a red background with one star and four stripes that reflect the one dot and four dashes for its signal.

Morse Code Flag for the Number 0: _ _ _ _ _

The Morse Code Zero Flag has five stripes that represent the five dashes for zero.  Additionally since it uses the metric order for colours, white is the background which coded to white with its contrast indicator being black.
