If you repeat it enough times, you'll start to believe it.
It's called subjective conditioning.
If viewing prints in sunlight, they will generally be lit by "normal" white light, at a temperature of around 5500k. Artificial lighting can vary. Common light bulbs range in temperature from about 2500k to 4200k, which is quite warm. Flourescent lighting, which is less common in homes, is hard to nail down. Often cooler, 6500k to 7200k or so, they also output greener or violet lighting. Sometimes they come in warmer variants that are more similar to standard bulbs. Calibrating to a warmer white point helps balance out differences between what you see on screen, and what you see in print.
a blue screen is like 6500k.. its not natural lighting and it's an unnatural image. get over it kid. (I assume your a kid because if your not I'm absolutely shocked by your ignorance).
