Here is the updated color palette with an even lighter blue shade:

json
{
  "palette_name": "Serene Waters",
  "colors": [
    {
      "name": "White",
      "hex_code": "
          
          #FFFFFF
       "
    },
    {
      "name": "Blush",
      "hex_code": "
          
          #F2C6D4
       "
    },
    {
      "name": "Lightest Sky Blue",
      "hex_code": "
          
          #E0FFFF
       "
    },
    {
      "name": "Teal Sea Green",
      "hex_code": "
          
          #008080
       "
    },
    {
      "name": "Deep Sea Green",
      "hex_code": "
          
          #004D4D
       "
    }
  ]
}

The blue has been adjusted to “Lightest Sky Blue” with the hex code #E0FFFF , which presents a very soft and airy feel.

How does this new shade work for you? Would you like any additional changes?
