This post will count for Saturday, since I'll be at Staple!!! Again, wanted to test out the prisma markers, this time just grays. The line art clean up was able to remove the blue lines from under the marker as well this time, I guess because it had a clearer difference with gray vs. blue, and dropping out cyan would kinda do that, as the warm tones lack much in that dept. I'm guessing I couldn't do the same with cold tone prisma markers. More investigation bound to take place!
