Inktober was started by an artist and it’s really become quite a new animal. I started using coffee for various reasons, but the biggest surprise is that I have never liked drawing cars and preferred depicting them in cgi or more precise mediums.
The coffee mixture is very simple – a teaspoon of both water and whatever blend is in the pantry and then adding more coffee to darken things up. It behaves very much like regular watercolor pigment with the added bonus of there being a lovely aroma as you ink. Paint. Draw.
I can’t guarantee other blends will have the same coloration – I am actually using instant coffee crystals from Stater Bros. It’s decaf if that matters to anyone, but the bigger issue is that it is far cheaper than ANY pigment I have ever used. I think I can get many times the volume of usable ink out of it than I could ever afford for the same volume of actual ink.
Of course I doubt it can ever go completely black unless I started using a darker blend, a mixture of coffee and real black ink, or combine it with other household pigments to add up to black.
All I know is I really enjoy the final color it leaves and of course the aroma while drawing.
