You are correct Graeme there is a big difference in the color temperature of daylight. I thought 5600k would have been pretty close... I'm learning that I will have to white balance each and every time. I used the 18% gray card and got a reading of 4578 Kelvin in bright sunlight with no cloud cover. With cloud cover its around the 5600k ball park.

The funny thing is that I don't remember this type of cast on my older 5600k clips shot with non Build 20. More accuracy in Build 20?
