Thanks for this. It took me some investigating to see that the color bar is chr(9608) * 8, a.k.a. 0x259F / "█" / "Full Block".

I made myself this helper, which puts them on the same line, and 6 "spaces" wide, by default:

from IPython.display import Markdown, display

def swatches(colors, sep=' ', width=6):
    display(Markdown(sep.join(
        f'<span style="font-family: monospace">{color} <span style="color: {color}">{chr(9608)*width}</span></span>'
        for color in colors
    )))
