Moodmark Paint

This small jar, contains enough paint to apply
moodmarks to one creature. The paint is dabbed
on the face in spots or markings that resemble the
eyes of insects or spiders. Applying the paint
takes 1 minute. For the next 8 hours, the marks
change to reflect your mental state. A creature
that can see you and makes a DC 10 WIS(Insight)
check can discern whether you are happy, sad,
angry, disgusted, surprised, or afraid, as well as
the main source of that emotion.
