yes same spot, 12 hours apart
one is during 8Am daylight (about 5600k)
the other is during 8Pm house lights (about 2500k)
yes, that completely changes the color of the paper, and the beams
because of the difference in ambient light color temperature
notice for example any one beam under both conditions
say the sw45k (4500k 219b), it looks pink compared to daylight, but looks blue compared to warm white
similarly the 3500k almost looks white compared to warm white, but looks rather orange compared to daylight
make sense?
the difference in ambient light color temperature alters the white balance of my brain
so an LED I like during the day, may not be my first pick in the evening
for example, these two lights
during the day, I like the 4500k LED "better", because it looks "whiter" (closer to the CCT of the ambient light)
at night, my Color Temperature preference changes to warmer, and then the light that looks yellow, does not, instead it looks closest to "white".
white is not always the same color temperature
