I've been looking for a nice, light tone gray to use for creating backgrounds. I used this ink today and it looks like it will be just what I was looking for. Not too light and not too dark; just right!
I wanted a very light ink to do water less coloring. Also for a subtle background with stencils. I also needed something that would work for my name on the back of my card creations. Both colors fit this bill. Different shades but perfect.
