Coloured Light

I think that different coloured lighting should be added to torches and sea lanterns. Yes, I know there is the soul torch, but that doesn’t actually emit blue light, it’s just the torch that’s blue. I understand this would be complicated to make, but I think that coloured light would make a HUGE difference to atmospheres in builds. As a bonus thing, I would propose a mob called the Soulcatcher, that would go around caves, looking for different coloured souls for you. You could then use these to change the colours of torches and sea lanterns. You could also simply dye the Soulcatcher to search for specific colours.
