Colored Redstone

To make the dyes more useful, allow to change the color of redstone with different dyes. For example, 1x dye for 1x colored redstone dust. The name would change accordingly (bluestone, greenstone, whitestone...) and would work ONLY with the same color. Possibly, with a "multi-color" one (or leaving the normal redstone as such) that will work with every other dust.

So, people (like me) with cramped space with lot of redstone stuff can have them working together without risking that activating one circuit will trigger other ones. It would also allow to better decorate with theyr own blocks. Torches, comparators and repeaters could work with every other "dust" as well.

As example, blackstone dust (aka black redstone dust) could give a great effect in a coal mine.
