Here’s an updated color palette with a background color added, suitable for a horror theme:

json
{
  "palette_name": "Eerie Night",
  "colors": [
    {
      "name": "Blood Red",
      "hex_code": "
                            
                            #A50000
                        "
    },
    {
      "name": "Ghostly White",
      "hex_code": "
                            
                            #F0F0F0
                        "
    },
    {
      "name": "Midnight Black",
      "hex_code": "
                            
                            #000000
                        "
    },
    {
      "name": "Graveyard Green",
      "hex_code": "
                            
                            #4A4E00
                        "
    },
    {
      "name": "Spooky Purple",
      "hex_code": "
                            
                            #4B0082
                        "
    },
    {
      "name": "Creepy Gray",
      "hex_code": "
                            
                            #808080
                        "
    }
  ]
}

In this updated palette, I’ve added “Creepy Gray” as a background color. This neutral shade can serve as a base, allowing the other vibrant colors to stand out while maintaining the overall eerie theme.

Would you like more suggestions, or do you have a specific use case for this palette in mind?
