Trying to learn a bit of Pandas and now want to add a index cause prefer it over just numbers, and also wanna learn how to do it ofc, but it won’t work

If I don’t add the index the code works fine and I don’t get NaN values and get the hex codes and RGB codes.

I haven’t found any solucion yet can’t find anything that resolves my problem.

Thanks in advance

When I run this code I only get the index and the rest turns into NaN, why?

import pandas as pd 
import numpy as np 


def colors():
        colordata = pd.DataFrame(  
         {

        "Hex code": [ 
                        "#000000",
                        "#FFFFFF",
                        "#FF0000",
                        "#00FF00",
                        "#0000FF",
                        "#FFFF00",
                        "#00FFFF",
                        "#FF00FF",
                        "#C0C0C0",
                        "#808080",
                        "#800000",
                        "#808000",
                        "#008000",
                        "#800080",
                        "#008080",
                        "#000080"
        ],

        "Decimal Code (RGB)": [ 
                        "(0,0,0)",

                        "(255,0,0)",

                        "(255,0,255)",
                        "(192,192,192)",
                        "(128,128,128)",
                        "(128,0,0)",
                        "(128,128,0)",

                        "(0,0,128)"   
        ]
                }
)
        df = pd.DataFrame(colordata, index = [   
                                "Black",
                                "White",
                                "Red",

                                "Yellow",
                                "Cyan / Aqua",
                                "Magenta / Fuchsia",
                                "Silver",

                                "Navy" 

                        ])

        print("What color do you want information on?")
     
        print(df)
                
colors()

Here is what I get when I run the code
