Black & white clusters ("coloring" without colors)

[Gephi_ASDLR]

Dear all,

I am new to this forum, thank you in advance for your much desired help.

I wish to publish some of my work in a journal that doesn't take graphs in colors. Here's my problem : I used Gephi modularity statistics to generate clusters in order to classify the different nodes of my network.

Is it possible to visualize the classification (the four clusters i'm getting) WITHOUT the use of colors (but instead, for instance, a set of black & white geometrical patterns) ?

Awaiting your replies.
