I'm working on a small study to compare the honing qualities of the various types and colors of Escher hones.
I took some photos comparing the color of the Escher's I have here. They are arranged from most blue on the left to the most yellow on the right. Also included is a photo of the most blue next to the most yellow.
I haven't done any color correction yet. They were taken under 3200K photo lamps. The stone surfaces are wet to better show the color. #7 is a labeled blue-green.
Many thanks to Rich, Howard and Lynn for their help. I think saying that I have HAD is the understatement of the century!
I thought maybe someone else might find this interesting.
