Darkening

"Darkening" is the term used for when the area around a Machucan's eyes darken in shade. Darkening can occur when a machucan is aroused, flustered, embarassed, or anything which might cause a human to blush. Darkening, like blushing can have various degrees from barely noticeable to eyeliner bold. When a machucan darkens to a fair extent the shade also carries down to their cheeks giving off the same look as a human would blushing. A machucan often darkens with the same color as their hair but with deeper or de-saturated tone. (Imagine Ucije with teal green eyeshadow) In the conceptual stage of machucan culture, it was considered to have members of the Dazmund court wear elaborate eyeliner makeup in order to mask darkening so that their emotions cannot be read. This idea was later scrapped to the archives.

(I'm sure if any machucan saw an emo person walking around they'd think that person was seriously flustered about something...)
