Bluuuuuuuuuuuuuuuuue
green. Wow - dats some pingy tank right there. If I may be so bold as to offer advice, if you were to get a couple of tubes of oil paint in, say, dark blue and dark green, and a bottle o odourless turpentine, you could level up that there tank's paint job by giving it a quick delineating wash*. It'd take maybe 30mins, but would look awesome, done in moderation (and not slapped all over it.)
As for Xbox boy, he's the gunner offa the venom, and will soon have a large splinter cannon attached to the firing assembly he's holding. Xbox controller indeed
Standard dark Eldar head, btw. I just gave him some serious goth issues with the paintjob is all.
*ie just around the panel lines and rivets and suchlike.
