Nope - I'll have to take a close up photo - you will find that there is 4 colours on each tank.
With the Chimeras I painted the name plate on the side under the Lasgun ports
Plus on the rear and the right awnings I painted the Squadron colours and Tank Number.
But overall - I like a simple colour scheme, previous Chimeras had been painted up as Valhallan with a winter white\Green camo but I did not like it.
Then I started re-painting my Mordian Guard to be used as a Genestealer Cult Brood Brothers - so Blue (Jacket)and Purple (Helmet).
So decided to paint the whole of my Tank Company and Baneblades the same colour (Blue\Purple)
When it came to re-do my Catachan, I did not want to go with the Green camo and was planning on going to a
GW Campaign weekend doing Cityfight and so was born the Martian Defence Force (Red).
As you noted in the game they need a little more work.
Had planned on doing 3 Vendettas but ran out of time.
Im going to be using my whole Armoured Force for my 40th Birthday Bash - will have to take a picture of the whole lot and post it up.
