Final answer:
The color of the 'letter A' in the night sky when the governor dies is symbolic and depends on literary interpretation of the text's themes, rather than being a literal color.
Step-by-step explanation:
The question posed appears to be a literary or figurative one, likely pertaining to the symbolism or thematic elements in a text rather than a literal query demanding a factual color of a letter in the sky. The references to the night sky, emotions surrounding death, and the description of the night could be symbolically represented in the literature, possibly relating to themes of loss, contemplation of mortality, or the transcendent nature of the stars when contrasted with human grief. In the context presented, the color of the 'letter A' in the night sky when the governor dies would be subject to the interpretation of themes within the text and the use of imagery and symbolism by the author.
