New lights!!

Hey so I was playing Minecraft and thought of an idea that I think me and a lot of others would enjoy! First is colored lighting, it would be super cool if we could have different colored lighting instead of just white light, like the colors of the rainbow and it would also be awesome if you could add in a dim light, like a yellowish soft light that could still keep mobs out but not completely brighten the room PLEASE this would be so cool
