That's the thing with olive skin people - some olives are green and some are black.

Under sodium-vapor lights (or whatever type of light was used in that Home Depot parking lot)?

How would that work?

The Home Depots I've been to use metal halide in the parking garages. Color rendition is about 85% that of natural sunlight. That's about 20% better than your average cool white, warm white or even daylight fluorescent bulb.

If they're using non-color corrected high pressure sodium, color rendition is more along the lines of 21%.

Although, it takes the introduction of very little 'white light' to clean up the color distortion from high pressure sodium. If this construction worker saw the suspects in the wash from his back-up lights or headlights, that would be enough for him to get a pretty accurate description of them including their color.

The HPS luminares provide you with the raw lumens to eliminate shadows or darkspots and your headlights or back-up lights 'clean-up' the color.

Try it next time you're in a parking garage.

The ultra yellow light from low pressure sodium has a color rendition index of 3% that of sunlight and your headlights will clean that up easily, as well.
