Hello Carl,
I've done the Celt last year and greatly enjoyed the build and painting of it.
(thanks for the compliment Quang)
I used the box art as a reference and used my imagination on the folding of the plaid (Sagum) for it's folds and creases make it impossible to draw straight lines.
You don't have to use the same colors on the Sagum.
Bright colors were favorite by the Celts so Green, Yellow, Red etc.
Remind that tartan came from these early types of plaid but no more than 3 colors were used. (on the crossing you'll get a mix)
First paint the base color and then start laying down the broad lines (slowly and careful) your pattern will form itself if you start with one line to make a center.
It will be necessary to loose a line here and there but with a bit of attention you'll figure out where that's possible.
Your Carnix looks great and with the little use of raw umber it will be outstanding. The tongue could also be done in a red, wood, or even a blue.
The personal jewelry would be Gold but keep in mind that it would contain Copper thus being in the Red Gold range.
Celts used a natural mix with lime to color their hair white (it's thought that the enemy would fear them for being ghosts).
There is some controversy on the use of tattoos or warpaint but if planning to do something like that use Blue only.
Have fun...
Willem
