Colored lighting fully(ish) implemented into levels for things (for coloring the player and 1st person weapons, & enemies, etc.).
I say 'fully'ish' because Hybrid appears to also colorize the walls, floors, and ceilings seperately, like how Doom 64 does, and I haven't got to those yet, so those still need to be implemented, but I'm happy enough to at least have the general colors and lighting, and will probably add the rest later on after beta/alpha release.
