I’ve adjusted the Light Purple to a more saturated shade to ensure it stands out better against a white background. Here’s the updated palette:

  "colors": [
    {
      "name": "Deep Blue-Violet",

    },
    {

    },
    {

    },
    {
      "name": "Orchid",

      "hex_code": "

    },
    {
      "name": "Vibrant Yellow-Orange",
      "hex_code": "
          
          #FFB74D
       "
    },
    {
      "name": "Bright Orange",
      "hex_code": "
          
          #FF9800
       "
    },
    {
      "name": "Soft Orange",
      "hex_code": "
          
          #FFB300
       "
    },
    {
      "name": "Light Coral",
      "hex_code": "
          
          #FF7F50
       "
    }
  ]
}

In this revision, Light Purple has been replaced with a more saturated Lavender shade to improve visibility against white backgrounds. Would you like any further changes or assistance with this palette?
