<｜begin▁of▁sentence｜>### Instruction:
Given two graphs g1 and g2, with edges for g1 as [(0, 1), (1, 2), (2, 0)] and edges for g2 as [(0, 1), (1, 2), (2, 0)], and both graphs having vertex colorings color1 and color2 as [1, 2, 3] respectively, can you use the GraphBase.count_isomorphisms_vf2 function from igraph to compute the number of isomorphisms between g1 and g2 considering the vertex colorings?
### Response:
import igraph as ig

# Define two graphs, g1 and g2
edges_g1 = [(0, 1), (1, 2), (2, 0)]
g1 = ig.Graph(edges=edges_g1)

edges_g2 = [(0, 1), (1, 2), (2, 0)]
g2 = ig.Graph(edges=edges_g2)

color1 = [1, 2, 3]
color2 = [1, 2, 3]

# Count isomorphisms between g1 and g2
iso_count = g1.count_isomorphisms_vf2(other=g2, color1=color1, color2=color2)

print('Number of isomorphisms:', iso_count)
