The red is a very close match to the Red Shadow colours.
The green is a perfect match to Z-Force green.
Its so perfect in fact that i dont even paint over it once primed.
Go to : http://www.warlordgames.co.uk and go to the (army painter) section.
The green is the 'green skin' shade. Its £8.99 a can and last a good while.
Hope this helps you all out.
Steve.
