Here’s the revised color palette with a lighter and less saturated blue that complements the overall aesthetic:

{
  "palette_name": "Masculine Oak",
  "colors": [
    {
      "name": "Black",
      "hex_code": "
                            
                            #000000
                        "
    },
    {
      "name": "Forest Green",
      "hex_code": "
                            
                            #2E3A2B
                        "
    },
    {
      "name": "Burnt Sienna",
      "hex_code": "
                            
                            #E45D2D
                        "
    },
    {
      "name": "Light Slate Blue",
      "hex_code": "
                            
                            #A3B8D1
                        "
    },
    {
      "name": "Warm Antique Gold",
      "hex_code": "
                            
                            #D6A25B
                        "
    }
  ]
}

The new Light Slate Blue provides a softer contrast while still fitting within the masculine and warm theme of the palette.
