Thank you for your precise guidance! I’ll adjust Nine’s grays by decreasing the blue value slightly. Here’s the final palette:

    },
    {
      "name": "Nine - Medium Gray (9)",
      "hex_code": "
                            
                            #A3B0B2

    {

      "hex_code": "

                        "  // Adjusted grayish light gray with a hint of blue
    }
  ]
}

In this final version, Nine’s grays have had the blue value decreased by 5. I hope this is exactly what you are looking for! If you have any more tweaks or requests, just let me know!
