Is there a way to make the transition lines on workflow diagrams darker?

[Tom Velarde]

The transition line are barely visible on the workflow diagrams. How can I make them all darker so they are more visible?

[Brant Schroeder]

The lines are svg paths that are rendered by the browser.  Embedded in the path is the color which is most likely contained somewhere in the JIRA code.  There is no setting that I know of that will allow you to change the color and custom CSS will not work as there is no attribute other than path to tie it to.

I was hoping the color scheme might impact it or maybe a browser setting.

I quite agree that the lines are too faint.   It would be really nice if the colour was configurable.

I really struggle to see them too.

Me too - impossible in fact.
