- Prime   Fine Primer White Spray  or equivalent. Any pure white will do. 
 - Coat the entire miniature, including the base, in   Soulblight Grey  .
 - As I had based this keyword with textured tile-style plasticard, I also dotted some watered-down   Poxwalker ,   Mortarion Grime  and   Targor Rageshade   to the base, for some contrast (as the minis will be mostly white like their basing). 
 - Drybrush the miniatures   Matt White  or equivalent (any white paint suitable for drybrushing). 
 - Coat the skin with   Guilliman Flesh  
 - Coat the masks/etc, other surgical elements, with   Aethermatic Blue  
 - Coat the leather areas in   Wyldwood  , and the other fabrics with varying   Basilicanum Grey  and   Black Legion  . I painted the doc's tie with   Gryph-hound Orange  
 - Coat the hair areas in varying   Skeleton Horde  ,   Cygor Brown  ,   Targor Rageshade  etc. 
 - Coat the remaining and to-be-metal parts with   Black Legion  ; then, stipple some   Thrash Metal  onto the latter. 
 - Basecoat the syringe 'liquids' and eyelenses with   Matt White  . Coat the syringes with   Volupus Pink  and coat lenses in   Nighthaunt Gloom
