Your comment about the moon seeing itself as red is a curious statement.
How do you know that the moon sees itself as red? Have you had some kind of communication with it? When the moon is full, or even close to it, I've seen its aura and haven't seen any red in it. What I saw was a very lit up blue aura on the moon's edge. The aura extended far away from the moon and the colours faded and turned into a 'mist'. Those colours were mostly green and indigo.
I drew what I saw but coloured pencils can't do any justice for the aura.
The colour red has many meanings and I've never associated it with fear.
This says that black symbolizes fear among other things.
I'm curious how you came to your conclusions as to why red symbolizes fear and how the moon views itself as red.
But ask now the beasts, and they shall teach thee; and the fowls of the air, and they shall tell thee:
Or speak to the earth, and it shall teach thee: and the fishes of the sea shall declare unto thee.
Job 12: 7 and 8 (KJV)
