To create a final, streamlined color palette, I’ll remove a few colors while keeping a balanced selection. 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": "Deep Orange",
      "hex_code": "
          
          #E56B2E
       "
    },
    {
      "name": "Pale Yellow",
      "hex_code": "
          
          #F7E5A4
       "
    }
  ]
}

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