RGB light levels instead of white light

Currently the light level is from 0 to 15, but this is a white light. Colors are only present through the colors of the blocks or via a colored fog (underwater or in the nether for example) This gives a dull constant atmosphere in the game. I imagine a light system based one the 3 basic colors: red, green, blue. Only the sun would provide a white light in the middle of the day, but every light source could have its own RGB light levels. Torches would light things in orange-yellow. Lava in orange-red, redstone in red. Sea lantern in turquoise. I think this would enhance greatly the ambiances in the game. The existing light base mechanics could be based on the sum of the 3 colors in order to be the same as today in white light. But we can imagine some funny mechanics depending on the color of the light.
