I’ve added the pale yellow to the color palette as you requested. Here is the updated 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": "Emerald Green",
      "hex_code": "
          
          #137A5F
       "
    },
    {
      "name": "Berry Pink",
      "hex_code": "
          
          #D6396D
       "
    },
    {
      "name": "Dusty Rose",
      "hex_code": "
          
          #D8A39E
       "
    },
    {
      "name": "Soft Peach",
      "hex_code": "
          
          #F4C4A0
       "
    },
    {
      "name": "Pale Yellow",
      "hex_code": "
          
          #F7E5A4
       "
    }
  ]
}

This palette now includes the cheerful pale yellow, adding a bright and sunny touch to the warm tones. If you have any more adjustments or need additional assistance, feel free to ask!
