Based on your description of a dark Greek mythology game with a red moon, green vegetation, and beige/light brown broken pillars, here is a color palette that reflects those elements:

{
  "palette_name": "Mythic Twilight",
  "colors": [
    {
      "name": "Red Moon",
      "hex_code": "
          
          #A52A2A
       "
    },
    {
      "name": "Dark Green Vegetation",
      "hex_code": "
          
          #2E8B57
       "
    },
    {
      "name": "Beige Pillar",
      "hex_code": "
          
          #D8CBAF
       "
    },
    {
      "name": "Shadowed Night",
      "hex_code": "
          
          #4B3C32
       "
    },
    {
      "name": "Mystic Black",
      "hex_code": "
          
          #1C1C1C
       "
    }
  ]
}

This palette captures the essence of a dark atmosphere intertwined with elements of nature and ancient ruins.
