Braille Letter S Flag, Sierra

I is 9th letter of the alphabet, and an easy way to remember this fact is to think of the I-9 assassin droid from Star Wars.  Nine is assigned the colour pink as pink is final number before the zero reset.  So red is combined with white to give the pink colour of completion.

Braille Letter P Flag, Papa

Since P is the 16th letter of the alphabet it gets the colours coded to 1 and 6, which are red and indigo respectively.  Remember that red is the 1st colour of the rainbow while indigo is the 6th colour of the rainbow.
