Thanks Tiago.
This 'no' answer is the first data point I needed.
I will continue to investigate. If necessary I will send a simplest possible sample (assuming I don't find the answer while building the sample...)

Again, this is not possible to say if you will not show us what you are
doing. I don't even know what function you are calling. Is it
graph_draw() or NestedBlockState.draw() [guessing from the figure you sent]?

The problem could be anywhere from a typo in your code to a bug in the
library, and it's impossible to say without context. Please try to
understand this.

But if the question is simply: "Does graph-tool add random colors and
ignores my input per design?", then the answer is no. It's just hard to
see how this question is useful to you.

Best,
Tiago
