Got it! I’ll replace Deep Red with a darker and distinct shade of red while keeping the red theme. Here’s the revised palette:

json
{
  "palette_name": "Rainbow Delight Expanded",
  "colors": [
    {
      "name": "Vibrant Yellow",
      "hex_code": "
          
          #FFB71B
       "
    },
    {
      "name": "Sunset Orange",
      "hex_code": "
          
          #FF6F20
       "
    },
    {
      "name": "Bright Red",
      "hex_code": "
          
          #FF3D00
       "
    },
    {
      "name": "Crimson Red",
      "hex_code": "
          
          #B71C1C
       "
    },
    {
      "name": "Royal Purple",
      "hex_code": "
          
          #9C27B0
       "
    },
    {
      "name": "Bright Magenta",
      "hex_code": "
          
          #D5006D
       "
    },
    {
      "name": "Grass Green",
      "hex_code": "
          
          #4CAF50
       "
    },
    {
      "name": "Sky Blue",
      "hex_code": "
          
          #2196F3
       "
    },
    {
      "name": "Bright Cyan",
      "hex_code": "
          
          #50D1FC
       "
    },
    {
      "name": "Light Lavender",
      "hex_code": "
          
          #E1BEE7
       "
    }
  ]
}

In this version, Deep Red has been replaced with Crimson Red, which is a darker and more distinct shade of red. Let me know if there are any other adjustments you’d like to make!
