quick intro

rainbowpy is a simple tool to handle building color maps from a list of colors. There will likely me more features in the future.

You can create a YAML file and place it in:

$HOME/.rainbowpy/custom_maps.yml

which will be read on import will add the created color maps to your mpl library:

The format is

apples:
  - "#28CC5F"

import matplotlib.pyplot as plt
import rainbowpy

N = 1000
array_dg = np.random.uniform(0, 10, size=(N, 2))
colors = np.random.uniform(-2, 2, size=(N,))
fig, ax = plt.subplots()


ax.scatter(array_dg[:, 0], array_dg[:, 1], c=colors, cmap="iri")
