Another stupid lighting question

[vintner]

Can some one explain to me how the # of Kalvins listed on the package my bulbs came in relates to the red and blue spectrum? Like one package says 5000K/bulb, is that a red or blue spectrum bulb? I'm refering to 4ft fluoros. Or does K's even refer to the color spectrum? If not, how do I know if the additional bulbs I plan to buy are putting out primarily red or blue light?
Thanks Vin

Color temperature - Wikipedia This should take you to the scale, here is a pic of it though.
