I crafted 1 shield for every style yesterday except for glass, xivkyn or any new orsinium styles. I dyed each one with several different colours and noticed that the majority of the shields are barely taking on any color. To the point that dying many of the styles was completely pointless.
There were about 2-3 that took the color VERY well and I was happy with that. I understand that some armor doesn't take dye as well, such as leather, (which is a whole other issue itself), but I made each shield out of the same materials and each one took colour VERY differently, again with most taking almost no color. I tested with reds, blacks, whites, pinks, greens, blues, purples, oranges. I went through the majority of my colors at the station.
I feel that this needs to be revisited and tweaked so the dyes come through better. I may go craft them all again and re-dye so I can post which styles didn't play nice with the dye station. I'll edit with a link to a gallery if I decide to craft and re-dye and upload pics of each one.
