this might ave been asked befor, but kuros can have different coloured kuronium right? I know Ashira has obsidian, but could colours like gold and such work? I think a kuros with kuronium the same colour as oxidized copper would be super awesome!

OOC : Yep! Kuronium comes in different shades of color, though hues of silver is the most common and what most associate Kuros with. Each color has a slightly different property to it; black being the heaviest and strongest type of Kuronium, therefor the most rare of the metals.
