Changing default colors

Hi Prof. Peixoto,

gt version: 2.98

os: ubuntu22

python: 3.13

Question:

can we change the default colors list to a user specified one while drawing a BlockState() for instance?

MWE:

import numpy as np 
from scipy import sparse
import graph_tool.all as gt

adj = np.array([
    [0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 1, 1, 0, 0, 0, 1, 0, 0, 0],
    [0, 0, 0, 1, 0, 0, 1, 1, 0, 0, 0],
    [0, 0, 0, 0, 1, 1, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 1, 8, 9, 1],
    [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
])
adj = adj + adj.T
g = gt.Graph(sparse.lil_matrix(adj), directed=False)
b = np.array([1, 2, 2, 2, 1, 1, 2, 2, 1, 1, 1])
state = gt.BlockState(g, b)
state.draw()

Attached is the output of the MWE.

Instead of having blue and light blue colors, can I specify some other colors while drawing?

Many thanks,

As it is explained in the documentation, every parameter you pass to the BlockState.draw() function gets passed to the graph_draw() function. Please look at its documentation about changing the layout properties: graph_draw — graph-tool 2.98 documentation
