This is a black drake hide jacket dyed red. As you can see, the bits you can't dye, are black;
Now this, is what mine looks like;
black drake hide jacket, leather.
In this pic i have dyed what i can black, but the trimming is sickly green... it should be the same black as the first image.
I used a metal brush on it when painting armour became possible, it had a colour rune on it before.
The metal brush removed the rune colour.. i fear it may have removed the trimming colour as well.
I cannot return it to the previous colour because you can't dye that part of it.
