seems like the projectile is just an emitter, so couldn't that be recolored similar to how laser A works with bricks?
I'm looking into it at the moment. The ski is colored according to your spray can color, I'm trying out if I can do the same with particles.
Edit: I don't think you can do it considering the ski item is blue when you hold it. When you are on the skis, it's a vehicle. If you could color items dynamically for by the client I think Badspot would have made the skis work like that.
For future reference getColorIDTable(%client.currentColor); gets the decimal RGBA value of the currently selected spray can color.
