Revelio - Blue Glowing Objects

[Corpx2]

After using the revelio spell some abjects glow different colors. (ie. yellow, blue)

I know the yellow glow means you can pick it up or loot it but, what does the blue glow mean?

Thx!

interactable or you can use a spell on it

Ye, blue is either an interactable object example a box that you can use spells on to get up to a higher place or a puzzle/something else start area (won't say more since it might be spoilers).
