The below will give random 12 colors to each bar chart. How should I modify it to make the colors consistent across each of the three bar charts?
p1.vbar(x=Segment, top=df['Population'], width=0.9,
color = random.sample(Viridis256,12), fill_alpha=.75)
p2.vbar(x=Segment, top=df['Size'], width=0.9,
color = random.sample(Viridis256,12), fill_alpha=.75)
p3.vbar(x=Segment, top=df['MPG'], width=0.9,
color = random.sample(Viridis256,12), fill_alpha=.75)
