Change color of iron chain to match iron block

The new copper chain, bars, lanterns, and torches all have the same color and patina phases as all of the other copper blocks. However, the "iron chain" now looks too dark and has lost continuity with the other iron blocks. The iron trapdoor, door, bar, block, pressure plate, and even the iron bar/nugget entities all have a lighter, white-ish color. The iron chain now looks too different from the other iron family of blocks.

Please either lighten the chain color or darken the other iron blocks to match. This would also include the chains on the hanging signs and the lanterns.

Also would be really cool to see patina for iron as well, but I'm certain this has been suggested before. A world in which copper develops patina from elemental exposure, but iron doesn't rust is just... mass hysteria!! :)
