Based on your request for a primary color, a secondary color, and additional colors suitable for text contrast (including lighter and darker versions), I’ve refined the palette to focus on these aspects. Here’s the updated color palette:

{
  "palette_name": "Focused Contrast Palette",
  "colors": [
    {
      "name": "Primary Lime Green",
      "hex_code": "
          
          #85c548
       "
    },
    {
      "name": "Secondary Sky Blue",
      "hex_code": "
          
          #99dbf8
       "
    },
    {
      "name": "Darker Lime Green",
      "hex_code": "
          
          #5B9A3A
       "
    },
    {
      "name": "Lighter Lime Green",
      "hex_code": "
          
          #A5D55E
       "
    },
    {
      "name": "Darker Sky Blue",
      "hex_code": "
          
          #007B9D
       "
    },
    {
      "name": "Lighter Sky Blue",
      "hex_code": "
          
          #B2E4FF
       "
    }
  ]
}
