1) Create a new activity (say "Race")
2) Base it on an existing (say "Run")
3) Change Accent Color of Race (to say, orange)
Expected behavior: Accent color of menus and the lines in between fields on the Data Screens will change to orange, just like the main icon and the Navigation you-are-here arrow dow
Actual behavior: Those items remain Run's color. Note if you change Run to say, pink, those *Race* items now change to pink. But note the Navigation you-are-here arrow remains orange.
