How to print only line color from lineplot in seaborn?

This is my code

fig, ax = plt.subplots(figsize=(50, 30))
sns.lineplot(data=dataframe, x='A', y='B', hue='C', ax=ax)

Then it appeared like this

There is a blue line and it is painted in light blue as if it spreads around it.

I only want to see the color of the straight line

like this for example

What should I do?

>Solution :

That’s the confidence interval that you see. You can supress it by passing ci=None:

fig, ax = plt.subplots(figsize=(50, 30))
sns.lineplot(data=dataframe, x='A', y='B', hue='C', ax=ax, ci=None)
