Here’s an updated color palette based on your Jujutsu Kaisen theme while maintaining the overall essence. I’ve made subtle alterations to enhance the palette.

    },
    {
      "name": "Spirit Purple",
      "hex_code": "

    },
    {
      "name": "Demon Black",
      "hex_code": "

    {
      "name": "Tokyo Sky Blue",
      "hex_code": "
          
          #3A92D0
       "
    },
    {
      "name": "Jujutsu Gold",
      "hex_code": "
          
          #FFD700
       "
    }
  ]
}

This updated palette retains the core colors while refreshing their tones to enhance vibrancy and cohesion.
