Sure! Here’s the updated color palette, replacing the Amethyst Purple with a dark red:

json
{
  "palette_name": "Cool Jewel Tones",
  "colors": [
    {
      "name": "Emerald Green",
      "hex_code": "
          
          #005B5C
       "
    },
    {
      "name": "Sapphire Blue",
      "hex_code": "
          
          #003B5C
       "
    },
    {
      "name": "Dark Red",
      "hex_code": "
          
          #5C0016
       "
    },
    {
      "name": "Deep Teal",
      "hex_code": "
          
          #003D3F
       "
    },
    {
      "name": "Charcoal Gray",
      "hex_code": "
          
          #2A2D34
       "
    }
  ]
}

Now the palette features a rich dark red that adds warmth and contrast to the cooler tones.
