That is pretty cool. Since less and less cartoons, animes and 2.5d games (and of course more technical applications but I love 2d entertainment ) are being worked on by hand, this type of research is a big step in making them more streamlined and natural.
Hope the artists get more respect though. At least for animes, there are stories of employees being locked in their office until they finish, paid dirt salaries and therefore have no personal time with family and friends and for leisure.
That reminds me, I’m going to enable custom palettes and premade palettes of mine into Autofill Coloring Book. Adds to Projects in Github/Reptorian1125/gmic-community
