Color nodes based on attribute(column in data table) in cytoscape

Question

[rickbeeloo13]

I merged to networks (MPK3 and MPK6 regulated proteins) and uploaded this in Cytoscape. Know I have a column for these two called source which is MPK3 for the MPK3 proteins and MPK6 for the MPK6 proteins. I want to color the proteins based on the value in this "source" column(attribute) I saw some answers on this site but these were from old versions (and I'm just new using cytoscape) so I hope someone can help me out with this. to summarize:

• MPK3 in source --> color red
• MPK6 in source --> color green
• BOTH(not sure If I have to determine this in front or if cytoscape can figure this out if I have one protein and two rows which each have a different value for the "source") --> blue

update
I figured out how to do it, but I can't figure out how to fix it when there is both a red and blue color to give it a green color for example?

You can easily have nodes with two colors: assign one color source to the node rim (using style > border paint) and the other to the inside (style > fill color). You may need to increase the size of the rim (style > border width).
