I have a growing Imperial Guard army. Air Cadia, Black and Tan. Pretty standard for the most part.

But along came Scooter. Now I’m trying to figure out how to make my Mars Pattern Warhound Titan fit in with the color scheme of my Guard. If I could get it to work with my SOBs, so much the better. Just thought I’d throw this out to see if anyone had any (or have any links to) keen ideas for Titan color schemes.
To see what I’m talking about, here is the link for my Guard WIP thread (The Tweaker's Guard WIP).
And here is the link to the Titan WIP thread (A Tale of Two Titans -WIP).
