Certainly! A darker green can add a more sophisticated and professional touch to the palette. Here’s an updated color palette with a darker shade of green:

{
  "palette_name": "Medical Innovation",
  "colors": [
    {
      "name": "Deep Blue",
      "hex_code": "
                            
                            #051650
                        "
    },
    {
      "name": "Sky Blue",
      "hex_code": "
                            
                            #A4C8E1
                        "
    },
    {
      "name": "Forest Green",
      "hex_code": "
                            
                            #2E5B5C
                        "
    },
    {
      "name": "Charcoal Gray",
      "hex_code": "
                            
                            #333333
                        "
    },
    {
      "name": "White",
      "hex_code": "
                            
                            #FFFFFF
                        "
    }
  ]
}

In this updated palette, “Forest Green” ( #2E5B5C ) replaces “Mint Green,” providing a richer and more robust green that enhances the overall professionalism of the logo.
