A new note was added
recommending that the visiting
team’s dark jersey be the darker of
the school’s color scheme or black.
 Light blue, light gold and light silver
visiting uniforms continue to be
problematic since they are difficult
to differentiate from the home white
jerseys.

Not made illegal, just guidance away from getting new ones I guess. Kinda like the division line and center circle being properly marked.
