If I might make a humorous aside before I begin, I'm afraid that to me the modern version of Doctor Who is a bit like the films of The Lord of the Rings: my love is reserved for the original, in this case the Hartnell-to-Radagast, I mean McCoy, era (McGann too), and I'm extremely skeptical of almost everything in the modern interpretations. My mind is reeling at the thought of Professor Tolkien's work being at all improved by having similarities to the writing of Mr Russell T Davies...

Anyway.

Saruman seeks to see what it is made from and make something new.

Personally I see Saruman's "of Many Colours" routine as being symptomatic of a descent into darkness: first the light is broken, then it goes out. Consider, if you will, Morgoth in Valaquenta: "He began with the desire of Light, but when he could not possess it for himself alone, he descended through fire and wrath into a great burning, down into darkness." To me this act of refraction on the part of Saruman evokes the decay of motives which emphasises him as a feeble imitation of his diabolic role models, much like his attempts to forge his own Ring: "for all those arts and subtle devices, for which he forsook his former wisdom, and which fondly he imagined were his own, came but from Mordor".

This is another example, I would argue, of how Saruman was merely an imitator of Sauron; the Dark Lord had achieved the same thing with Trolls, the Olog-hai: "they could endure the Sun, so long as the will of Sauron held sway over them."
I personally don't see anything different or new about Saruman's activities, just inferior replications of the evil of Sauron. That his servants needed protection from the light (if this was not a mere effect of them being bred with Men) to me symbolises his evil. It is not an act of mastery; it is a compensation for one of the shortcomings of rebellion - an anathema for and weakness to something holy and good. I would suggest that, much like Sauron in the Second Age, Saruman still had "the relics of positive purposes" at some point in his plan (although I very much doubt that these were still present by the time of the Scouring of the Shire). "Sauron had, in fact, been very like Saruman, and so still understood him quickly and could guess what he would be likely to think and do." (Morgoth's Ring p.396) In this way I tend to see Saruman's fall, with its ring-making and many colours, as a sort of sped-up, rushed version of Sauron's own, and correspondingly fragmented for its brevity and Saruman's relatively lesser strength.
