Coloured lantrens/lights and lighting/light

Since the Vibrant Visuals are both "Minecrafty" but also look realistic, it would be cool if the lights and light colour would be coloured. I know that Mojang is busy, but adding more colours in the Minecraft would be very good for redstoners (because of Red, Green and Blue option for making coloured redstone computers) and for education, since all technological displays use Red, Green and Blue micro lights and pixels.
