I think the animation is way too fast, which makes it incredibly noisy. Half speed and only in the non-green variant it'd be an OK effect.
The explosion-coloured explosion is IMHO way better than the green version.

emerald splash!

white or light yellow isnt a bad idea tbf but honestly i think its better to just have 2 variants than pumping even more into the game

the original concept art was just the green variation called emerald explosion, i thought it would be nice to have a more general explosion variant aswell so went forward with it. idk i dont rly think having one green variant is an issue especially when some of the gen 1 effects people point to as examples of great effects do the exact same thing

i really like the orange, the green really just feels like "hey trader mains!!! hey look at the neon green!!". Hear me out, add a white or nice yellow, and if you really want that vibrant color, do the in game team colors :D

Adding colored variants to unusual has existed since the very first effect. Take Burning Flames and Scorching Flames for example.

The green shouldn't have been here.

original concept was green, i made a regular explosion variant

Why green?
