Arm/refined gold/ other sprite sheets display on dupes face while putting on hat

When a dupe puts on a hat, a variety of sprites will appear across their faces. Breif testing has show me the following:

3rd level farming hat causes arms to appear

3rd level construction causes hair styles to appear

Grilling causes both arms and possibly the sprite for gold or lead

Supply 2 causes an unknown, difficult to see sprite sheet to appear.
