I apologize for the misunderstanding. Thank you for your patience. Here’s the revised palette with Burnt Sienna shifted to a redder hue, along with proportional adjustments to the other colors to maintain harmony across the palette:

    },
    {

                        "
    },
    {
      "name": "Warm Olive",
      "hex_code": "
                            
                            #717C3A
                        "
    }
  ]
}

In this palette, the colors have been adjusted in proportion to the shift of Burnt Sienna to create a more cohesive look. Thank you for your guidance on this, and I hope this meets your expectations better. Would you like any further adjustments or assistance?
