Colored ingots but not colored armor

[Pringles]

In website it's said that armor can be in 9 different hues. But everytime I make armor using colored ingots, I get usual iron armor (not colored). Used Shadow Iron and Dull Copper ingots to make chainmail and platemail armor, but non-colored armor is being produced. Tried smelting and got iron ingots instead of colored ingots.

Mining 100%, Blacksmithy 75.9%. Tried both crafting menus (T2A and other), but result is the same.

Is that a bug or some kind of feature?

If you have different types of ingots in your backpack, then you have to set your crafting menu to the ingot type you want to use. Did you do that?
