Thank you for your patience! I’ve increased the saturation of all the colors slightly and added a hint of blue to Nine’s grays. Here’s the refined palette:

                        "  // Dark gray with a hint of blue
    },
    {
      "name": "Nine - Medium Gray (9)",
      "hex_code": "
                            
                            #A9B2C0
                        "  // Medium gray with a hint of blue
    },
    {
      "name": "Nine - Light Gray (9)",
      "hex_code": "
                            
                            #D3D9E0
                        "  // Light gray with a hint of blue
    }
  ]
}

With these adjustments, all colors are now slightly more saturated, and Nine’s grays carry a subtle blue tint. I hope this hits the mark! If you have any more tweaks or suggestions, let me know!
