These are just the most popular spectrums/kelvin temp. Usually anything under 3500k is warm white (yellow) and above it is daylight (blue).

However, if you have the space and ability to vent well, pick up a 400 watt HPS. You'll be glad you did, and it's only about $150 shipped on HTG. Well worth it and you barely notice a change in your electrical bill (about $10/month) while seeing a vast improvement of bud production.
