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?
