I’ve darkened the purple color in the palette while keeping the overall muted theme intact. Here’s the updated color palette:

json
{
  "palette_name": "Muted Luxury Luncheon Elegance (Darker Purple)",
  "colors": [
    {
      "name": "Muted Teal",
      "hex_code": "
                            
                            #4B9D8E
                        "
    },
    {
      "name": "Muted Navy Blue",
      "hex_code": "
                            
                            #2C3E50
                        "
    },
    {
      "name": "Muted Cyan",
      "hex_code": "
                            
                            #008C94
                        "
    },
    {
      "name": "Dark Muted Plum",
      "hex_code": "
                            
                            #5B2E91
                        "
    },
    {
      "name": "Muted Aqua",
      "hex_code": "
                            
                            #A4D6D4
                        "
    }
  ]
}

This palette now features a darker muted plum that adds depth and richness while maintaining a refined look for your luxury luncheon.
