Hi there guys; I'm having some problems with the scheme of my IG army, I've painted some tanks in fortress grey and added some bestial brown dust to them thinking about a mechanized regiment which comes from a desert planet (maybe a dust-desert planet). I built my guards using catachan sprues but using cadian heads instead, and here comes the trouble, I'm looking for desert schemes wich includes grey tones and no one convinces me. So if any of you have any idea about it, I'll be very pleased to read it.
Here are some photos of my tanks and an example of my count-as Harker:
Thanks for reading
