Peter,
This is where I have found a lot of my information:
http://www.stamp-collecting-world.c...s_1852d.htmlThe color is tricking me too. To the naked eye, it appears to be an orange/yellow....and the paper has a similar hue. These pictures don't show the color as well as the picture on my other post. I think I meant that there are 3 varieties of color/paper...but maybe there are more. But what I did read is that the gutter between the stamps is not common.
Also, here is the previous topic I posted for quick reference:
