Dalek Scientific Division
From Tardis Wiki, the free Doctor Who reference
The Dalek Scientific Division was a high-ranking group of Dalek Scientists in the hierarchy. Their needs overrode all other orders and concerns in at least two missions. (AUDIO: The Genocide Machine, Return of the Daleks) A Chief Scientist was leader of the Scientific Division. Science Daleks were claimed to be silver, though the Eighth Doctor met a green Dalek scientist once. (AUDIO: The Dalek Tapes)
Dalek Scientists during the Last Great Time War possessed distinctive markings on their casings which were pointed out by the War Doctor on Asteroid Theta 12. (AUDIO: A Thing of Guile)
The Scientist Daleks of the New Dalek Paradigm were ranked by their orange colour scheme. (TV: Victory of the Daleks)
