Select Orb Colors: used a widget iterator instead of a walker

Browse Source 
The documentation indicates you're not really meant to use the walker directly.
They're part of the implementation of the iterators. They could be used directly,
as shown here, but this is shorter.

(cherry-picked from commit aca7d4e6df4648ff45f48b6acb9e643de8c05103)
