Hail, Pinco and friends! I ran into this today when setting up a barkeep and a vendor through a contract of employment. (Haven't tried with a rental contract). In Pinco's UI, I can customize the vendors, but when I attempt to change a color (by clicking the item - hair style, for example, or half apron - and then clicking Color), nothing happens. The color picker gump does not show up. When I switched back to the Default UI, the color picker worked properly and I was able to customize colors. FYI!
