Created a sandbox to play with new meshes and textures. Made two new actors where I only specified values on the first page (ID, Name, Short Name, Race) then placed them in a new cell with only a bench. It's quite obvious that the default facial settings aren't being transmitted to the body.
At first I thought it was the meshes and textures I'd been using so I removed the meshes and textures folders from my Data folder. No effect. Then I wondered if something else had messed up internally so I took Steam offline and moved the High Res texture packs out. Same deal.
Figured maybe the defaults don't work so I modified the female actor. Under the Character Gen Parts tab I specified "SkinHeadFemaleBretonComplextion_Age40" under Face Complexion then changed the Preset under Face Tinting Color to "HumanFemaleSkinWhite05". On Character Gen Morphs tab I set Nose, Mouth, and Eyes to type 10. Back in game I could see the color and feature changes yet they still didn't get mirrored by the body.
On a Side Note: When previewing the Head I could see these chances as I made them. After changing the Zoom Speed to "0.01" I was able to zoom in on the Full Preview... yet that didn't show any of the changes I made. In fact, going back to the Parts tab, Full Preview didn't render any of the changes to Base Head Parts either. *shrug*
Moved the Hi Res stuff back in then went on the offensive. Figued the engine might require clothes to render skin correctly. I attacked Orgnar and Delphine inside RiverwoodSleepingGiantInn. Under the Inventory tab I set the Default Outfits of their base objects to "None". Back in game when I coc'd in, Delphine got clothes back (from a script I'm guessing) yet Orgnar stayed undressed. It was difficult to tell since his long hair style got in the way, so I changed it from Nord06 to Imperial1. Then ran into the setnpcweight bug.

But is this true, that a body will only render face colors/tints when armor is placed? The seam appears less noticable with some sort of clothing specified. Very new to modding and the Bethseda tutorials are very introductory. The Creating an Actor tutorial only touched on the seven or eight fields required to get one going.
To my "creative brain" having to place an article of clothing doesn't make sense. The entire body should be drawn then the clothing placed over it. Yet from a performance stand-point it might make more sense to render only the default texture then change it only if required. Or perhaps this is a "bug" in the sense that if nothing is placed on the body, the body is never tinted.
I need to do more reading and poking around but I'm wondering if anyone else has noticed this and there's some checkbox I forgot to tick. TIA!
