ColorWheel behaves in the same way, so maybe ColorArea has a bug and should return "No color format applied." when no color was assigned.

It does appear that Color Area is the one missing this "no format" return, which points to you being right. However, we do want to ensure that users are able to get a quality experience from our elements regardless of their input. This might make a good addition to #2308 where we could have DEV MODE warn on this reality but still return a color to ensure that applications "just work". Thanks for submitting this!
