[FONT=&quot]I took the advice of all the DIY'ers and made my own. I am new to this and was wondering which color cards to use. It looks like blue is the workhorse, but what would you use green for? My conditions are low and florescent lighting.[/FONT]
 
Looks like you've had a long dry spell on answers.

Pale green is specifically for balancing out standard florescents. It gets the greenish cast out .

Or you can experiment on very odd white balancing color cards (purples, yellows, bright greens, etc) in different lighting. It helps to understand what types of color do what in certain lighting, and it yields some trippy results sometimes. :)
 
ive never tried purple yello or brite green. but i use my warm cards all the time and trust me it helps. the card that seem to be my work horse is the green card. the blues seem to bring in more red unless im doing something wrong.

Your results and understanding of the results are correct. Using a color balance source that is blueish (like a warm card) will result in red being more dominant in your shots since blue is being reduced.

The way that it works is that the color reference presented to the camera is used to establish the relative levels of Green/Red/Blue, so if you give the camera a reference that has more blue, it will reduce the blue gain to compensate. Now any subsequent images will be captured with reduced blue (and appear to have more red). The results are complementary to the color reference used to balance the camera. A color wheel will give you an idea of what will happen for any color reference used to balance used to balance the camera. Just look across to the opposite side of the wheel to see what color will be emphasized by your shifted reference.

I have used a lot of different color references to get specific, in camera, color effects for certain shots. A great source of these are the color samples that you can get from paint stores.
