And his helmet 
@burvantill i dont do what jake parker does as often, i use “hue saturation” in photoshop first and select “red” or “blue” (depending on what pencil you’re using) from the drop down and put brightness to max or saturation to zero, or both. then i use the “levels” feature because I don’t like how photoshop messes with my lines so it’s always different for the second step.
Another thing im starting to do for time and sanity is draw it on an ipad or clips studio or whatever, print it on card stock in blue or orange (as @Jake-Parker suggested but I might change to bristol because my printer has a special slot for fancier paper and i want to use pen nibs) ink on card stock or on lightbox, rescan it and get rid of the blue/orange in photoshop. This way i can have original inked pieces that i can look at and go “oooo pretty”
