ok i dont really like the star thing on the top but its still pretty good

Oh! And, last comment (sorry). If you wanted a name for a team-colored variant, you could call it Alexandrite Aurora! Since that's a gem that changes colors (red/green/blue) depending on the type of light hitting it!
Zultanite is also another good contender, tho it typically only turns green, yellow or pink.

On the topic that the comment section is having, I really do like how this unusual combines 3 effect concepts in one, since it's calm enough & gives sufficient space for each particle

THESE NORTHERN LIGHTS UNUSUALS ARE SO PRETTY OH MY GOD

I wouldn't mind if the two were combined as a team-colored variant; I deliberately chose the color schemes so they would work either way. The reason I chose to post as three variants rather than two really just does come down to not being able to come up with a name I liked for a team variant lol. Thanks for the question!

I do have a question regarding variants; why not combine Ruby Aurora and Sapphire Aurora to be a singular team-coloured effect? I think it will lesson the clutter. Instead of having three separate effects, you can shorten it down to two.

I love multiple things in one, if one thing doesn't work, you can use another thing that fits the loadout better.

It tries to be too many things at the same time. This is just my personal opinion but I don't like the direction tf2 workshop is going with doing these "3 in 1" types of cosmetics and effects. Tangent aside just make a nice aurora effect if you are going to make an aurora effect. If you are going to have a cloud or space in the effect have just one of them and have it in the background.

I love the simpsons.
