I've recently tested out the 5* Phantamos and Arcana guns, and noticed when I charge the bullet, the blast colour when it hits or blows up is still the same light blue colour as it was with Blaster, or any other gun from the line of Valiance!
I'm assuming it would be the same for every other new blaster gun with a different theme of colour.

Is it meant to be like this? I reckon it would be nice if they changed that visual effect to match with its gun's theme.
