I have a question about imported English kersey(blue/grey). Would the color of items imported be the exact same color or would they very by contract? My research so far has indicated that there may be a few shades difference. It is very hard to tell from pictures and I have no way to study origionals. I have also read every article I can find on imported kersey on the forums and could find nothing. I ask because the blue/gray offered by different high quality vendors are often nothing alike.
