Food Coloring as Ink Experiment
So I had a little IRL art experiment with food coloring. I mixed red and blue and used it straight as an ink, nothing else in it. It works fairly well. The poor drawing is a faded brown now, but these are the results of a fairly fresh drawing. I used a liner brush for most of the linework and a dip pen for the gun. Scanned into Rebelle3 and added some watercolor. I also converted the ink to black and, man, can I not wait for Friday to come so we can go to the big (15,000 people) city an hour away and get some real ink. So if you can't get ink, and you don't want to deal with complicated recipes, just get some food coloring and mix some colors together until you get the hue you want. It works in a pinch.
