I wouldn't necessarily say it is that simple. We have seen dust used for a few factors so it could be its application.

For example red isn't fire but it causes a rapid increase in localised energy. Which would heat things up through friction if used for a fire effect or, as potentially seen in the white trailer, would give her a short burst of strength.

Light blue would do the opposite and rapidly decrease local energy. Easiest example would be creating ice, not too sure I've seen light blue used for another purpose however it is possible.

Dark blue seems to work on manipulating kinetic/momentum energy, either starting or stopping. How Weiss uses dark blue in the series for her "air step" and in the white trailer it pushes the giant armour into the air then binds it there. This also applies to red increasing the effect as seen in ep8.

Yellow dust would manipulate electrical energy. Not much more to be said, either electrocution or a powerful static cling.

Violet is a strange one however I put it down to essentially "telekineses" which is hard to manipulate but very powerful. Hence how Weiss could render the sword from the giant armours grip under specific conditions however Glenda can manipulate it much better while seeming to specialise in that dust.

White is like the jack of all trades dusts. It can be used for near enough any effect as needed which would be great in a pinch and when combining effects for a powerful strike however you get stronger effects using the specific dust for the effect. Which is why Weiss used white a fair amount in the white trailer however as time goes on the is getting more used to using specific colours on the fly.

If I am right about dust working on the molecular level and not just "wild effect" then green and orange would be similar. If you look at it through the rainbow it starts with red giving a great vibrational energy boost, orange would give a different kind of energy (maybe potential energy), yellow gives electrical energy, green would be neutral or decrease energy, light blue would decrease it further/vibrational decrease, dark blue/indigo allows manipulation with violet coming up the rear with stronger power. Nora's pink dust would be white and red combined creating controlled explosions. White dust could be used for basically all effects and black dust/smoke would be a controlling/corrupting effect.
