Using a vacant makeup room, airbrushes and compressors were set up along with several versions of green and yellow temporary-tattoo ink. Reel Creation product line was used because it had a suitable pigment level for the job. Other supplies for the test included a hair dryer with a cool setting, makeup cape, and additional Reel Creation tattoo colors to adjust the bases.
The actors’ skin was thoroughly cleaned with isopropyl alcohol 99 percent to remove skin oils so that the makeup would adhere evenly. Moisturizer was not applied—it could possibly cause the tattoo inks to streak and easily come off.
