Changes to the copper armor trim and new redstone copper block

In the latest minecraft preview, we are introduced to a new item called resin that can be used on armor trims to get an orange color. But with that, the copper armor trim is now useless. Here is my idea: Make copper amor trims have a little dark green added to the orange so it can get some variety. I have another suggestion regarding copper. It should have a new use and here is my idea: Copper wiring! Instead of using redstone, you can use a copper wire that works like string to transfer redstone signals in air without having to use a support block for redstone. In my opinion, that it would be a really good addition to redstone and copper.
