“…Then, through color extraction of different types [56] of Luanzhou shadow play, such as classic figures and appliance field films, we summarized three colors with the highest frequency of application: red (C: 37%, M: 97%, Y: 83%, and K: 3%), yellow (C: 1%, M: 29%, Y: 81%, and K: 0%), and green (C: 85%, M: 48%, Y: 84%, and K: 3%), as shown in Figure 13. Finally, the head shapes of Luanzhou shadow play characters are presented as examples [57], including the basic images of male, female, painted face, old, clown, beard, great, and fairy and monster roles, as illustrated in Figure 14. These were applied in the design of cultural and creative products to highlight the facial features of shadow play and to popularize science about the head shape of all kinds of shadow play so as to reduce the cognitive burden of users.…”
