Based on your request to change the green color ( #00C030 ) to a dark blue color and also make the hair dark blue, here’s a new color palette reflecting these changes. The dark blue color I have selected is #003366 .

Here is the updated color palette in JSON format:

{
  "palette_name": "Dark Blue Transformation",
  "colors": [
    {
      "name": "Charcoal",
      "hex_code": "
          
          #303030
       "
    },
    {
      "name": "Black",
      "hex_code": "
          
          #000000
       "
    },
    {
      "name": "Light Gray",
      "hex_code": "
          
          #F0F0F0
       "
    },
    {
      "name": "Light Pink",
      "hex_code": "
          
          #F090F0
       "
    },
    {
      "name": "Dark Blue",
      "hex_code": "
          
          #003366
       "
    }
  ]
}

This palette features a charcoal base, complemented by black and light gray, with the transformation to dark blue replacing the original green.
