We would like to share some test results for our new ND filter with a color temperature meter. Per our testing, the color shift is within ±~100K.
Before testing, the meter read:

ND4 reading (EV Stop: ~2.1):

ND8 reading (EV Stop: 3.0):

ND16 reading (EV stop: 4.2):

ND32 reading (EV Stop: 5.1):
We hope this little test can help someone who wants to buy or already owned the filters.
