LoE window coating colour changes by sunlight intensity? – GreenBuildingAdvisor

So apparently the LoE coatings look different depending on the lighting… please explain!

We have LoE 366 on all the windows on 2 sides (triple glazed units). I noticed the sun coming in had a sort of sickly green hue… at 12:30pm, in southern Ontario, in late March. See the photo below showing an open window beside the fixed window. What a drastic difference!

Oddly, I didn’t notice this during the winter (but windows were closed) and I’m trying to understand how this works. Maybe I only noticed it now because I was looking at our new table, but AI tells me the coating will look most green during strong midday sun like this because of the intensity… it’s confusing because the morning sunlight really does not look green, I’ll have to try another test with an open window at a different time.
