Kelvin rating would be best, what color it was listed as(warm white, sunlight..), or the brand might help if it's a bulb manufactured for aquariums.

Some are naturally darker than others, but you should only really worry if they turn a really light color, which will most likely mean they are experiencing some kind of stress. I'm not your neighbor, you Bakersfield trash.
