i drew it exactly the same way i would have if he weren't a ghost:
then i carefully cut him out of the merlin layer:
and moved him to his own, semi-transparent layer:
(multiply layer, 50% opacity)
on another new layer, i copied over just the outline, reusing this hex value of merlin's robe (0054a6) for a little added continuity:
(normal layer, 50% opacity)
on yet another separate half transparent layer, i filled in all of uther's area with solid white:
(normal layer, 50% opacity)
i did the same thing with a very bright blue (66ffff), but turned the transparency down more:
(normal layer, 25% opacity)
with both layers visible, uther looks translucent and mostly white with a blue tint:
then, turning the color layer back on combines pure ghost with the natural color of a living king:
it's by no means professional, but i think he reads as a ghost so it works for me. it's also super easy to accomplish and has the added bonus of being totally fun to screw with the layers independently.
