Clearly the inferior Klingon mind is unable to grasp the Romulan color palete. Why I must explain it to the likes of this Targ sniffing son of a Ba'Tek is beyond me, however, I will try to type slowly so it can be understood.
Romulans view color differently than the lessor species, and to us the color pink is visually appealing. It appears in a wide variety of forms from uniforms to starships.
The sheep is an ongoing metaphor in which we compare the mewling weak human species to its closest animal companion....the placid sheep. While you humans may fancy yourselfs warriors, and decendants from higher primates; the Romulan High Command knows the truth. Your weak species will follow any leadership no matter how poor and incompetent, and while the Klingons show some warrior spirit they complicate their lives with needless honor rituals.

Punisher: Do you think they bought it? I mean I have to explain my affinity for sheep somehow...

Oh crap.
Umm... we'll be right back after I execute my communications officer. In the meanwhile, please enjoy this video of cute fluffy kittens being executed for high treason (Cuteness being a capital crime in the Romulan Empire)
