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:

    {

                        "
    },
    {

    },
    {

      "hex_code": "

                        "
    },
    {
      "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!
