Cold weather Is this coolant coming out exhaust???

Started my truck (05 6.0) up to today to warm it up to change the oil. I noticed what appeared to be coolant like coloured water coming out the exhaust onto the frest white snow. To put my mind at ease I took a little bit of coolant out of the degas bottle and poured it on the snow. To my horor the colour was very very close. Further investigationg has revealed this. Coolant level has not changed. No noticable coolant pressure in tank. No coolant taste in what ever is coming out.

What I would like is someone to check for me is this. In the cold weather states does anyones truck emit a yellowly rusty water like substance out of the exhaust on warm up. I am thinking that it could be rust / carbon mixing with the condensation and being blown out? Please, please someone put my mind at ease.

No excess white smoke. No burning antifreeze smell, no excess presures in cooling system, no coolant in the EGR hole

Sounds like normal condensation to me. When an exhaust system cools down it condenses water on the inside. When you start back up the water runs out the tailpipe. It even happens down here in NC.
