<｜begin▁of▁sentence｜>### Instruction:
Given a graph with nodes 0 and 1 having the attribute 'color' set to 'red', and nodes 2 and 3 having the attribute 'color' set to 'blue', and an edge between nodes 1 and 3, can you use the NetworkX function 'attribute_mixing_dict' to determine the mixing between 'red' and 'blue' nodes?
### Response:
import networkx as nx

# Create a graph
G = nx.Graph()

# Add node attributes
G.add_nodes_from([0, 1], color='red')
G.add_nodes_from([2, 3], color='blue')

# Add edges
G.add_edge(1, 3)

# Get the attribute mixing dict
mixing_dict = nx.attribute_mixing_dict(G, 'color')

# Print red -> blue mixing
print('Red to Blue:', mixing_dict['red']['blue'])
# Print blue -> red mixing (should be the same for undirected graphs)
print('Blue to Red:', mixing_dict['blue']['red'])
