I do find it tough getting the right color with the leds. I have a Canon T3i, which I'm sure would have no problems taking the pics if I were to practice with it more.

Interesting statement. Kinda like saying, I have great pans, can't understand why my meals aren't much better - Only kiddin :)

You need to shoot perpendicular to glass, on a tripod, high ISO (for faster shutter speed), and use a grey card (or something similar in shot) for manual white balance or an expodisc kind of device. You could also shoot raw and play with white balance if you have software to do so.
