nicer engine flame/plume colors

the engine flames right now are just a simple orange or blue or white color, it would be nicer if it was more colorful like real life, for example methalox and hydrolox would have a little bit of red and pinkish colors like the raptor and the shuttle engines while keralox could have more red at the end of the flame like the falcon heavys flame, it’d make launches more spectacular and increase the quality of the game
