-* 2: secondary, next most important under normal situations
-* 3: tertiary, next most important under normal situations

-The following CSS variables define the main, public API for styling JupyterLab.
-These variables should be used by all plugins wherever possible. In other

-necessary. This enables users to change the visual theme of JupyterLab
-by changing these variables.
-
-Many variables appear in an ordered sequence (0,1,2,3). These sequences
-are designed to work well together, so for example, `--jp-border-color1` should
-be used with `--jp-layout-color1`. The numbers have the following meanings:
-
-* 0: super-primary, reserved for special emphasis
-* 1: primary, most important under normal situations
-* 2: secondary, next most important under normal situations
-* 3: tertiary, next most important under normal situations
-
-Throughout JupyterLab, we are mostly following principles from Google's
-Material Design when selecting colors. We are not, however, following
-all of MD as it is not optimized for dense, information rich UIs.
