Based on your preferences, I have created a new modern naval palette replacing the seafoam green with a darker red. Here’s the updated color palette:

{
  "palette_name": "Modern Naval Palette - Updated",
  "colors": [
    {
      "name": "Deep Navy",
      "hex_code": "
                            
                            #001F3F
                        "
    },
    {
      "name": "Ocean Blue",
      "hex_code": "
                            
                            #007BFF
                        "
    },
    {
      "name": "Dark Red",
      "hex_code": "
                            
                            #8B0000
                        "
    },
    {
      "name": "Slate Gray",
      "hex_code": "
                            
                            #7F8C8D
                        "
    },
    {
      "name": "Coral Red",
      "hex_code": "
                            
                            #FF4136
                        "
    }
  ]
}

Palette Description:

This updated palette maintains the classic deep navy and ocean blue, while the new dark red adds a bold and sophisticated touch, enhancing the overall modern naval theme. Slate gray continues to provide a neutral balance, complemented by coral red for highlights.
