No background color when using `Documenter.DiagramOptions#withColorSelector`

[rems]

I'm probably using it wrongly, but I can't make it work.

I ran the DocumenterTest and it doesn't seem to work.

spring-modulith/spring-modulith-integration-test/src/test/java/org/springframework/modulith/docs/DocumenterTest.java

Line 62 in b318a7e

.withColorSelector(it -> Optional.of("#ff0000")) //

(in this test, withDefaultDisplayName works as expected, though)

Do you have some documentation on how to color diagrams? I can't find any besides this test.

My use-case is to visually indicate:

• shared modules
• open modules
• deprecated modules
• wrong relationships between modules (like, cycles)

Can you qualify “it doesn't seem to work”? Ideally, do you have a test case that shows the PlantUML output not to get the coloring applied?

Thanks for your answer !

I'm not sure of how to write a better test than the one mentioned earlier (using commit fa6a8ee of this project). More specifically, I don't know what the generated PlantUML should look like. I'll check on structurizer project ; if you have some resources I could follow, that would help me.

By "doesn't seem to work", I mean there are no specific colors applied to the background.

On my computer, the output does not present any red background.
