    {
      "name": "Bright Yellow",
      "hex_code": "
                            
                            #FFD700

    },
    {
      "name": "Bright Orange",
      "hex_code": "

                        "
    }
  ]
}

This palette now features bright yellow and orange, adding vibrant accents to the warm earth tones. If you need any more adjustments or have other requests, feel free to let me know!
