The color of light, or color temperature, is rated in degrees Kelvin (K). Sunlight is the most efficient color temperature for the human eye, at approximately 4,000 to 5,500 K. Incandescent bulbs have a warmer (lower) light temperature, around 2,700 K, while HID and LED lights vary from 4,000 K all the way up to 8,000. Your eyes will thank you if you skip the purple HIDs and stick to around 4,500 K.
