Just curious, do you recall the difference in diameters?
2 Db is not necessarily a small difference, particularly over longer distances.
IIRC, insulation is pulled over conductors by running them through a vat and through an over sized die. The size of the die regulates the diameter of the insulation as well as centers it.
Of course, a molten insulation means that a variation of insulation thickness is bound to occur, since the molten insulation has to be maintained within a critical range in order to flow smoothly. One would think that any unevenness would manifest in all colors, though.
In my experimentation, I have noticed, particularly in using a thermal stripper, the properties of different colored insulation is quite different from each other. Apparently the color dye lots has a greater affect than most of us would realize. Indeed if the insulation is stiffer, twisting would be more difficult.
