Today I have a test model that I painted for my Dark Angels army.
I decided that my Dark Angels army needed a bit of a re-vamp with 8th edition. My current Dark Angels army was painted up in 3rd edition and were among the very first 40k models that I ever painted. As a result, they are looking a bit dated.
I wanted to the get the Primaris Marines painted up and decided they would do well in my Dark Angels army. I had a look at videos on Youtube and found the Dark Angels Hellblaster video and Dark Vengeance Tactical Squad from Warhammer TV to be very useful.
I painted them up with a variation on the colour schemes in the videos. I undercoated them with Caliban Green, then gave them a wash with Nuln Oil.
