I had an idea of having the option of glowstone being a different color and glow a different color. Now I dont know how this would be done but me and some people thought this would cool to have different colors. I also thought it would be cool if you could hook glowstone to a redstone circuit to use use a repeater so it flashes. One thing maybe to add if possible clear glowstone that changes colors when on a circuit. So if this is possible that would be great and leave comments and suggestions
Well, there is no mechanism for colored light, and notch has said that there probably will never be, and in order to change the way the glowstone appears, you would need to switch it with another block, or write a client mod. Someone can correct me if I'm wrong, but I'm pretty sure this is impossible.
Well, its a bit annoying since notch's code is all obfuscated, and then there's the fact you'd still need a server mod to make it work.
