Breaking down the new (and old) transformations

[TheMikado]

Actually Cold supports my opinion of them being the same layer of skin, since he doesn't have any pink parts and his skin continues trough the plating. Cooler does it too, as in both forms there is nothing suggesting he has different skin between over the elbow and under the wrist. Also, Frost has none of those either. Freeza is the not the only one with two-colored skin, so to say that the internal logic of his whole race is thrown out the window because he is "special" (obviously not, as Frost exists and is stronger than him) is just plain ignoring everybody else.
Chilled, for example, shows exactly how it's the same layer:

Spoiler:

But your chilled picture just proves my point interns of different textures and layers. If you look at the shading it shows it is distinct from the flat purple skin and not flush to it. Similar to how your fingernails would sit. Or the different layers of a turtles skin like I showed above. It can all be the "outer" layer but it has a different function and serves a different purpose.the skin on your ankle and the skin on the bottom of your foot both have different textures,color, and function if you had the skin on your ankle that you have on your foot you would constantly tear your foot open as you walk. My point was that the ribbed skin appears to be a hardened layer of skin and the white parts appear to be even harder shell like parts where the smooth base parts appear to be the weakest and most vulnerable parts. I suppose you could also say it's the opposite but it wouldn't make sense with the way the skin progression and even cooler and King cold are designed.
