Its not necessarily the color you see that you want for growing, its the spectrums you want, 6500k for veg & 2700k for flowering, a red or blue colored bulb will produce very little useable light for plants. This will explain it a lot better than I could: (--->CLICK HERE<---)
 
Thanks for the reply's and Information. I have a 100w hps I was just looking to add some CFL's to add to the wattage and get a better yield. Has anyone done this? I was thinking about 6 26w 2700k CFL's?

Yes absolutely, supplementing with CFL's is a very common practice especially with growers using low wattage HID's or no HID at all. Remember, as long as your temps and ventilation are under control more light= More Bud!

gotta remember that there is a massive difference between what we and plants use light for, as well as the organs that we use to make that interaction.

your link is all about how our eyes perceive light, and that isn't important to a plant.

plants have several photosynthetically active pigments that each have a relatively narrow band of light energy that they will respond to.

here's a link i just found that at a fast glance looks to nutshell a great deal of the information (aquarium people tend to know a great deal about artificial lighting) - http://www.americanaquariumproducts.com/aquarium_lighting.html
