Which does rather show the importance of using decent continuous spectrum
lighting of the correct colour temperature. Unless you like not being

to see things at home.


That's why you need daylight type bulbs at home.

Daylight bulbs are not continuous spectrum. As well as temperature some
bulbs also report colour rendering index.

It is also worth noting that the actual sections of the spectrum our
eyes detect differs for different people. So when bulbs produce a patchy
spectrum, what work well for one person may not work well for another.
