Selection of light fixtures, (lamps, lightbulbs) should be based on their CRI value (color rendition index). We are talking about the weather the lamp outputs the full viewable spectrum. A CRI of 100 outputs the full spectrum. You should shop for lamps that output a CRI of 90 or better. The CRI is often printed on the label of light bulbs and fixtures with lamps installed.

That being said, the human eye is remarkable in many ways. They have the ability to adapt to a wide range of illumination, both color and brightness.

This adaptation is unique for left and right eye. Please perform this experiment. Procure some colored filters. Colored cellophane wrapping paper works also. Place a red filter over one eye and look about at various objects. Now remove the filter, close one eye and look about. A few seconds later, swap the eye that is closed. This experiment shows you how powerful the eye/brain combination is to the various colors of ambient light. Try different colored filters. The filtered eye has changed its white balance. It will return to match the unpatched eye in a half hour. The color change is the complementary (opposite) color of the filter. Red – Cyan Green – Magenta Blue – Yellow. On way, the eye secretes a dye, visible purple (rhodopsin) that bathes the retina with a reddish-purple fluid that changes the sensitivity of the various rod and cone cells.

What I am telling you is, the color of the ambient light is not as important as a high CRI.

On a lighter note: Pirates are often portrayed with an eyepatch. This eyewear purpose is not what you think. Sailors prepared for their watch at night by placing a patch over one eye. This patched eye will dark adapt in an hour or so thus night vision out of this eye is maximized.

Kodak advises 5000K with a high CRI.
