    },
    {
      "name": "Dark Green",
      "hex_code": "
                            
                            #006400
                        "
    }
  ]
}

In this palette, the pure white and forest green serve as the main colors, while gold is suggested as a striking detail color that can enhance the overall look of your Aeldari army. Gold adds a regal touch and complements the green tones beautifully.
