The eyes (and brain) make complicated calculations millions of times per second. One of these is the perception of colors. Unless you have protanopia (color blindness) we all see colors slightly different. This can change throughout the duration of a day many times. Fatigue, bright light, low light, looking at a certain color object for a length of time, computer/smartphone use, and so on are factors.

But when we look at something under different light, like daylight (5000K) vs tungsten (2700K), our brain “auto corrects” to a somewhat neutral compromise. This can be good or bad.

When looking at color prints under different color temperature lighting, certain colors in a print may look slightly different. Our eyes can only do so much to compensate, sort of a general compensation.

To the left is a photo showing the same object (M&Ms on a plate) under different color temperature lighting. Your eyes, if you were looking at each separately, would do it’s calculation to make things look “normal”. But it’s also possible the red M&Ms will look quite different.

Food for thought.
