  "colors": [
    {
      "name": "Midnight Blue",
      "hex_code": "
          
          #0A3142
       "
    },
    {
      "name": "Aqua Marine",
      "hex_code": "
          
          #1B4D6E
       "
    },
    {
      "name": "Light Sky Blue",
      "hex_code": "
          
          #87CEEB
       "
    },
    {
      "name": "Powder Blue",
      "hex_code": "
          
          #B0E0E6
       "
    },
    {
      "name": "Sky Blue",
      "hex_code": "
          
          #00BFFF
       "
    }
  ]
}

This palette emphasizes light blue shades while maintaining the deep ocean feel with the addition of lighter tones.
