I am trying to change the color of the left nav bar in kibana 6.7.2.
I've opened up dev tools and found the class definition where the background color is applied.
I've found the _global_nav.scss file where the css is defined and edited it to a new color. When I stop and re-start the kibana server, the colour change is not respected.
I've read that you may need to delete the root/optimize folder in order to get css changes to be respected. Even when I do this the css changes are not respected.
How can I change these stylings?
