The expected genres of Buddhist art showing the Buddha, or Buddhist monks, and Confucian art of scholars in repose, or studying in quiet often mountainous surroundings follows general East Asian art trends. Nimbus colours are not necessarily gold, and may be suggested by lighter colours. Faces tend to realism and show humanity and age. Drapery is done with some to great care. The face is generally two-dimensional, the drapery three-dimensional. As in medieval and renaissance western art, drapery and faces are done often by two or three artists who specialize in one particular painterly skill. Iconography follows Buddhist iconography.
