To create a final, streamlined color palette, I’ve removed the orange, soft peach, and yellow as you requested. Here is the revised palette:

{
  "palette_name": "Earthy Warmth",
  "colors": [
    {
      "name": "Warm Beige",
      "hex_code": "
          
          #E6D5C3
       "
    },
    {
      "name": "Cocoa Brown",
      "hex_code": "
          
          #8B5E3C
       "
    },
    {
      "name": "Sage Green",
      "hex_code": "
          
          #A6B17E
       "
    },
    {
      "name": "Emerald Green",
      "hex_code": "
          
          #137A5F
       "
    },
    {
      "name": "Berry Pink",
      "hex_code": "
          
          #D6396D
       "
    },
    {
      "name": "Dusty Rose",
      "hex_code": "
          
          #D8A39E
       "
    }
  ]
}

This final palette maintains a warm and inviting feel with a good mix of earthy tones. If you have any further modifications or need more assistance, just let me know!
