I would think the brown or cyan dust that is used would increase the resilience of the umbrella allowing it to withstand the attacks that Yang dished out along with the others during the "Painting the Town" episode. It could be earth which would explain it's survivability.

As for the dark blue and light blue dust, well when i looked up dust on the sight it says that water is a primary type of dust along with fire (which we all assume is red), wind (green), and lightning (yellow).

However the elements such as ice and steam are considered "secondary" types of dust as it requires two types of "primary" types to be created. Ice (water and wind) Steam (fire and water)

I'm going to assume purple is gravity though and pure white dust could be the base form of just energy.
