I apologize for the oversight. Let’s shift the hue of Burnt Sienna to a slightly redder tone while adjusting the other colors accordingly for a cohesive palette. Here’s the revised version:

json
{
  "palette_name": "Hue Shifted Mellow Tones",
  "colors": [
    {
      "name": "Dark Teal",
      "hex_code": "
                            
                            #007C7A
                        "
    },
    {
      "name": "Reddish Sienna",
      "hex_code": "
                            
                            #A05238
                        "
    },
    {
      "name": "Muted Burgundy",
      "hex_code": "
                            
                            #8B4A63
                        "
    },
    {
      "name": "Olive Green",
      "hex_code": "
                            
                            #6A6E34
                        "
    }
  ]
}

In this palette, Burnt Sienna has been shifted to a more reddish hue, and the other colors have been adjusted to maintain contrast and harmony.

Is this more in line with your expectations? Would you like any further modifications?
