How to create a heatmap with dark purple

I am wanting to create a heatmap with dark purple as shown below:

darkpurple

Code:

import numpy as np
import seaborn as sns

np.random.seed(0)

uniform_data1 = np.random.rand(10, 12)

ax1 = sns.heatmap(uniform_data1, cbar_kws={'label': 'score1'}, cmap="BuPu")

I have tried cmap equal to "BuPu", "PuBu" or "Purples" but all didn't quite give me the right colour. Would really be nice if I could have the same purple colours as shown in the picture above.

Many thanks in advance.

import numpy as np
import seaborn as sns
import matplotlib
import matplotlib.pyplot as plt

np.random.seed(0)

uniform_data1 = np.random.rand(10, 12)

fig, ax1 = plt.subplots()
ax1 = sns.heatmap(uniform_data1, cbar_kws={'label': 'score1'}, cmap=sns.cubehelix_palette(8))
plt.show()

Output

I am not sure if sns.cubehelix_palette(8) is exact what you desire. You could look at seaborn's choosing color palettes page to find more options.

I think this is what you are looking for:

cmap=sns.cubehelix_palette()
