What color watch cap is worn with Army OCPs? Can the UCP (old ACU pattern) parka be worn with OCPs until the OCP parka is available?

The black watch cap is worn with the Operational Camouflage Pattern. To my recollection, OCIE in the Universal Camouflage Pattern is authorized until such time as CIF replaces it with OCP https://www.army.mil/article/159254/soldiers_can_mix_camo_patterns_for_cold_weather_gear

c. Fleece cap. Commanders may authorize wear of the foliage green or black fleece cap with the combat uniform in field environments when the Army combat helmet is not worn, on work details, or in other environments where wearing the patrol cap is impractical. Personnel wear the fleece cap pulled down snugly on the head. In order to wear the cap properly, the bottom edge (all) of the cap may be folded, but not rolled. Installation commanders will determine tempera- ture, wind chill, and extended duty time warranting wear of the cap in nonfield, nondeployed environments. The wear-out date of the foliage green micro fleece cap is 30 September 2017. The mandatory possession date for the black fleece cap is 1 October 2017 (see para 18-12).
