Based on your query regarding foundation undertones, I’ve created a color palette that reflects neutral, neutral-cool, and beige-neutral undertones. Here is the JSON representation of the color palette:

json
{
  "palette_name": "Neutral Undertones",
  "colors": [
    {
      "name": "Neutral Beige",
      "hex_code": "
          
          #D6CFC4
       "
    },
    {
      "name": "Cool Sand",
      "hex_code": "
          
          #C4BEB6
       "
    },
    {
      "name": "Creamy Almond",
      "hex_code": "
          
          #E4D6C7
       "
    },
    {
      "name": "Soft Taupe",
      "hex_code": "
          
          #B7A99A
       "
    },
    {
      "name": "Warm Biscotti",
      "hex_code": "
          
          #E5D0B5
       "
    }
  ]
}

This palette includes shades that cater to neutral and neutral-cool undertones, providing a versatile selection for various skin types.
