Light Color Metrics

Is this true?
_______________

2700K?3500K: Yellowish-white (similar to traditional halogen bulbs, looks old)

3700K?4300K: Warm white with a slight yellow hue (used in many OEM halogen and HID setups).
(Has the most range for the human eyes, whiter colors bounce around more)

5000K: Pure white (daylight white, looks more modern and cool)

6000K: Cool white with a slight blue hue (looks retro and cool but light/throw is below standard)

8000K+: Blue-white (often considered too blue for road use, more for aesthetics)

Yes, seems pretty legit.

This agrees with you.
