Morse Code Flag for the Letter L - Lima . _ . .

The Morse Code Flag for the letter L has an orange background.  Reason being, L is the 12th letter in the alphabet, and the background is based upon the ones column digit value of a letter.  The tens digit place value is ignored.  As orange is the second colour of the spectrum, we have an orange flag with black as the contrast indicator.  Since stars are coded to DOTS and stripes are coded to DASHES, this is the subsequent pattern revealed.  It coincidentally looks like a leopard pattern, so you can think L for the Leopard from Lima. 

Morse Code Flag for the Letter K - Kilo _ . _

The Morse Code Flag for the letter K is vexillologically natural, looking more like the flag of a nation-state.  But the stars and stripes of Morse Code Flags are coded to DOTS and DASHES.  Since these flags are read downwards, it spells out K in Morse Code.  Additionally K is the 11th letter of the alphabet, this makes the background red since the background colour is based upon the ones value of the letter. 

Morse Code Flag for the Letter J - Juliette

Morse Code Flags have stripes and stars that reflect the DOTS and DASHES of Morse Code.  Consequently the one star and three stripes for the letter J flag reference the one DOT and three DASHES of J in Morse Code.

Morse Code Flag for the Letter I - India . .

The Morse Code Flag for India is pink with two blue stars.  The two blue stars represent the DOTS in Morse Code.  Since this letter does not have any DASHES there are no stripes.  Also pink is coded to the number 9, so the background is pink. 

Morse Code Flag for the Letter H - Hotel: . . . .

The Morse Code flag for the Letter H has four stars.  In this case, stars represent dots.  Likewise there are no dashes, subsequently there are no stripes.

Morse Code Flag for the Letter G - Golf: _ _ .

The letter G in Morse Code is a DASH, DASH, DOT.  This translates to a STRIPE, STRIPE, STAR.  Since violet is the 7th colour of the spectrum and G is the 7th letter of the Alphabet we have a violet, or purple, flag. The stripes and star are yellow because yellow is the assigned contrast indicator for violet.

Morse Code Flag of the Letter F - Foxtrot: . . _ .

The Morse Code flag for the letter F has an indigo, or dark blue, background.  Reason being, indigo is the 6th colour of the spectrum and F is the 6th letter of the alphabet.  The star, star, stripe, star reflects Morse Code's DOT, DOT, DASH, DOT.
