Based on the themes of time, transience, and the cycle of life expressed in your query, I have created a color palette that reflects these concepts. The palette incorporates muted tones that evoke a sense of nostalgia and reflection.

{
  "palette_name": "Eternal Cycle",
  "colors": [
    {
      "name": "Dusty Rose",
      "hex_code": "
                            
                            #D4A6B1
                        "
    },
    {
      "name": "Faded Sage",
      "hex_code": "
                            
                            #B7C9B8
                        "
    },
    {
      "name": "Weathered Stone",
      "hex_code": "
                            
                            #A8A69D
                        "
    },
    {
      "name": "Soft Twilight",
      "hex_code": "
                            
                            #B8C9E7
                        "
    },
    {
      "name": "Whispering Grey",
      "hex_code": "
                            
                            #C4C4C4
                        "
    }
  ]
}

This palette captures the essence of nostalgia and the passage of time with its soft, muted colors.
