Blue is generally suggested, but I and many other use Red. With Red, you may need an impact tool to loosen them; my battery impact wrench with a swivel socket fits in just fine.

I have installed a lot of transmissions and engines over the years and have never used any type of thread locking compound on the torque converter bolts. To this day I do not know of any of these bolts backing out.
