Tri Gauge - Yak 52
Working when removed.
All tanks, pipes and gauges related to oil in the Yak 52, 50, 55 and 18-T are colored Dark brown. The top arc of the three indicators displays Oil temperature, denoted by the brown dot with the Celcius units mark.
Oil pressure is to the lower right.
Everything that contains, controls or indicates fuel in these aircraft is painted Yellow. The left hand gauge with the Yellow dot is Fuel pressure.
A different scheme is found on the connectors at the rear, but since both the receptacle on the gauge and the mating Cannon plug are color coded, it's easy to reconnect them properly.
