All the wares mentioned above were mostly in, or aiming to be in, some shade of green. Other wares which can be classified as celadons, were more often in shades of pale blue, very highly valued by the Chinese, or various browns and off-whites. These were often the most highly regarded at the time and by later Chinese connoisseurs, and sometimes made more or less exclusively for the court. These include Ru ware, Guan ware and Ge ware, as well as earlier types such as the "secret colour" ("mi se") wares, finally identified when the crypt at the Famen Temple was opened.
