I was of course going with the classic white trooper. Now anyone who's painted white will know that getting it smooth is a bit of a bitch, so building up the white steadily is key.
Firstly I undercoated the mini in Army Painters Uniform Grey (not pictured) Then I zenith highlighted with Vallejo Game Air Stonewall Grey.
Next I zenith highlighted with Vallejo Model Colour Off White.
Then lastly I zenith highlighted with Vallejo Game Air Dead White.
Then repeat! Its actually pretty quick to do so I can't see it taking to long to get these guys done.
Now the base colour is applied it's time to add the details. There's not may colours on a classic Storm Trooper thankfully! The gloves, weapon, and eye lenses were painted black. The black was then softly highlighted with some thinned grey to make it stand out a bit more.
Finally I added some orange to the shoulder pad. Now as not all Storm Troopers are squad leaders, this is a stage just for this trooper. I started with some orange mixed with dark red, then blended up the colour to orange over several layers. To properly finish it off I added some pure white highlights to the edges of the armour.
