So I don't really understand the "ember" particles. Is there different particles and how do you change the color?(I mostly want to know about the color "particle" : { "type" : "ember", "size" : "1.0", "color" : [255, 100, 0, 255], "light" : [150, 50, 50], "fade" : 0.9, "initialVelocity" : [0.0, 5.0], "finalVelocity" : [0.0, 3.0], "approach" : [0, 20], "timeToLive" : 2, "layer" : "middle" },
