Is it possible to change the color of the markers using the given of hexcode?

Code:

import plotly as px

hydrogen= px.scatter(plot_data,x='Calorific Value (kcal/kg)',y='Hydrogen (%)',title='Hydrogen Plot',
                    width=800,height=800,hover_name='Lab',color='Hexcode')

The goal of my code is to change the color of the markers to its hexcode. I think I have issue to my code. I was trying to do something like this

I want to make my 2d plot like this same hexcode to its marker color.
