NUD: Pubkey to colors

This NUD defines how to convert pubkey to colors.

Live demo

Why?

• npub is nonsense to display.
  • too long.
• npub1bla...bla is nonsense to display.
  • npub1 takes too much space.
  • ... means nothing.

Specs

• Uses hex pubkey.
• Converts 64 characters to 8 colors.
  • Splits 64 with 8 length chunks.
  • Converts each 2 in 8 into
    • Alpha (0-255 -> 0.0-1.0)
    • Hue (0-255 -> 0.0-360.0)
    • Saturation (0-255 -> 0.0-1.0)
    • Light (0-255 -> 0.0-1.0)
• Supports dark and light theme.
  • When Light is 1.0, flip the Light for light theme (0.0).

I still think it makes sense to display npub1...abcdef when no name is found, but having a standard color for each npub across apps would be a very nice thing.
