To ensure the darker muted teal meets the 5:1 contrast ratio requirement while maintaining a luxurious aesthetic, I’ve adjusted the colors accordingly. Here’s the revised color palette:

{
  "palette_name": "Luxury Luncheon Elegance (5:1 Contrast)",
  "colors": [
    {
      "name": "Darker Muted Teal",
      "hex_code": "
                            
                            #2C4D48
                        "
    },
    {
      "name": "Muted Navy Blue",
      "hex_code": "
                            
                            #1A2731
                        "
    },
    {
      "name": "Muted Cyan",
      "hex_code": "
                            
                            #007D8A
                        "
    },
    {
      "name": "Dark Muted Plum",
      "hex_code": "
                            
                            #4B2A6D
                        "
    },
    {
      "name": "Light Muted Aqua",
      "hex_code": "
                            
                            #B2E3E0
                        "
    }
  ]
}

This palette has been carefully adjusted to achieve the 5:1 contrast ratio, ensuring accessibility while keeping the luxurious theme intact.
