The short list of the matplotlib colors: blue, green, red, green/blue, yellow, purple, white, black, etc.

# Importing libraries needed
import seaborn as sns
import matplotlib.pyplot as plt
import pandas as pd

# Reading the file 
df = pd.read_csv('https://codefinity-content-media.s3.eu-west-1.amazonaws.com/c5b4ea8f-8a30-439f-9625-ddf2effbd9ac/bilibili.csv')

# Setting colors for the hue variable
hue_colors = {'woman':'red', 'man':'black'}

# Creating the 3-variable scatterplot 
sns.scatterplot(x = 'bill', y = 'tips', hue = 'gender', data=df, palette = hue_colors)

# Showing the plot 
plt.show()
