<｜begin▁of▁sentence｜>### Instruction:
As a caricature artist creating portraits at a large event, I have been asked to provide a unique touch to each drawing by incorporating the color of the subject's outfit. I need to use the "Zachary" graph to retrieve and print the color attribute values for all the vertices that represent various individuals at the event.
### Response:
import igraph as ig

# Load a given graph
g = ig.Graph.Famous('Zachary')

# Assuming the graph has a 'color' attribute for vertices
# Retrieve 'color' attribute values for all vertices in the graph
vertex_colors = g.vs.get_attribute_values('color')

# Print the color of each vertex
print(vertex_colors)
