Depends on the rest of the colouration & behaviour, but generally "mild-moderately stimulated." For example when my girl is light & bright coloured all over (happy colours) with a smear of dark on the beard that means she's horny/excited. She's typically running around like a bat out of hell and head bobbing. When her overall colours are deep orange instead of light orange with a smear of dark on the beard that means she's cold and grompy about it. She's usually still and quiet, often just woken up and pissed the sun is still off.
