We’ve always used 5K lighting to color correct.
Pantone sends out an email today that D65 is The Standard for color correcting.
I’ve only ever used 65K when using warm white LEDs as a backlight. And the number of times that’s happened I can count on one hand cuz it was an industry transition. Nowadays our lightboxes are Warm/Cool so can be dialed in.
Otherwise, it’s just the 5K lightbooth….
What do you all use?
