What is this orange stuff?

After dusting my crickets with Repashy Superfoods, this orange stuff grows on different areas of the enclosure. What is it? Should it be sterilized?

I'm not sure what it is but that orange stuff was always in my repashy crested gecko diet, so I'm interested know.

Repashy turns orange if it gets wet.

I'd guess it is the beta carotene or the marigold flower.
