Here’s the updated color palette without the white color:

json
{
  "palette_name": "Cricket Field - No White",
  "colors": [
    {
      "name": "Pitch Green",
      "hex_code": "
                            
                            #4CAF50
                        "
    },
    {
      "name": "Earth Brown",
      "hex_code": "
                            
                            #8B4513
                        "
    },
    {
      "name": "Sky Blue",
      "hex_code": "
                            
                            #87CEEB
                        "
    },
    {
      "name": "Ball Red",
      "hex_code": "
                            
                            #C0392B
                        "
    }
  ]
}

This revised palette maintains the essence of cricket while excluding the white color. Would you like to make any further adjustments or explore another theme?
