I think the full CTO might be what I'm envisioning, with an especially blue sky in the Golden Hour.
Remarkably, a much bluer sky does not change as much colorimetrically as you might assume. For instance, if you take a blue sky with 25,000 K (the highest value the CIE Daylight formula is defined for), my approach will give you 3562 K, only 156 K less, and still higher than Wayne’s result. Now, if you assume a 25,000 K sky *and* a *really* golden sun (4000 K, the lowest value the CIE Daylight formula is defined for), then you’ll get 3071 K.
