Type 99 has developed many variants throughout its service, each with different designations and colour variants. For example, there are Type 87, Type 95, and Type 03 patterns. The main variant is a four-colour woodland pattern with olive, green, yellowish-green and black. Type 99, like many other woodland uniforms with black, has been criticized for its use of this color, but once faded, it becomes dull and subdued, and therefore virtually unnoticeable.
