Log Panel - Coloring of Gutter

In the logs panel demo, the screen shot shows the left hand gutter colored red and green, what controls this behavior? Is it possible to customize more colors?

I would have guessed that the colors would be control by the presence common key words such as error = red, success = green, info = blue, warning = yellow, etc… but in my data that has those keywords, the color is always grey.

Grafana will search for a label named ‘level’ and apply color accordingly. Learn more in the documentation
