    },
    {
      "name": "Slate Blue",
      "hex_code": "

       "
    },
    {
      "name": "Turquoise Blue",
      "hex_code": "
          
          #00b2a9
       "
    },
    {
      "name": "Sky Blue",
      "hex_code": "
          
          #87ceeb
       "
    },
    {
      "name": "Light Aqua",
      "hex_code": "
          
          #e0ffff
       "
    }
  ]
}

This palette reflects the interplay of light through the layers of a blue tourmaline gemstone, starting with the deep, rich tones and transitioning to the lighter, more translucent shades.
