Dynamic block lighting colors

Instead of having the same color for all lighting, different blocks should emit different colors of light on the surrounding area. Ex. Torches emit a yellow-orange light, soul fire and its respective blocks emit a blue light, etc. This would make the game's visuals way more dynamic and realistic, as opposed to all blocks simply making an area brighter without any color change. The setting could either be directly related to the graphics setting (such as only being enabled if you have Fabulous! graphics enabled) or be a separate on/off setting in the Graphics tab. Plus, this would allow for the possible addition of dyed/different colored lamps.
