Here’s the reordered color palette for better clarity and aesthetic appeal, transitioning from lighter to darker shades:

{
  "palette_name": "Professional Harmony",
  "colors": [
    {
      "name": "Dusty Mauve",
      "hex_code": "
          
          #D6C1D3
       "
    },
    {
      "name": "Soft Peach",
      "hex_code": "
          
          #F5C2B8
       "
    },
    {
      "name": "Sky Blue",
      "hex_code": "
          
          #87CEEB
       "
    },
    {
      "name": "Lavender Gray",
      "hex_code": "
          
          #C4C3D0
       "
    },
    {
      "name": "Royal Blue",
      "hex_code": "
          
          #4169E1
       "
    },
    {
      "name": "Midnight Purple",
      "hex_code": "
          
          #4B0082
       "
    },
    {
      "name": "Slate Gray",
      "hex_code": "
          
          #708090
       "
    },
    {
      "name": "Charcoal Black",
      "hex_code": "
          
          #333333
       "
    }
  ]
}

This arrangement starts with the lighter colors and gradually moves to the darker shades, making it visually appealing for an Excel sheet or any other presentation format.
