Probably a combination of both, as well as adjusting the on-camera settings.
For example, I find that the auto White Balance gets it right most of the time, but I adjust the warmth of the light according to what look I'm going for. If I'm shooting sunsets, I'll warm the shot to A1 or A2 (amber), which deepens and brightens the reds and oranges of the sunset. I generally like the cooler, blueish hue when I'm shooting under moonlight, so I'll adjust it to B1 or B2 (blue).
I have no idea how the Canon options work, but on my Nikons you go into the white balance menu, select "auto", and there is a sub-menu to fine-tune the auto setting. On the D90, I can do it using the WB button on the back of the camera, and adjust it using the thumbwheels. I'm sure there would be a similar control on the Canon.
You can achieve the same thing in PP using photoshop or GIMP or whatever, but I generally find it easier and quicker to do it before I take the shot.
Give that a try, and see if the results are what you're looking for. You could also try changing the saturation control to "vivid" or "more vivid" if you're looking for deep, heavily saturated colours. Just be careful you don't go too far, or the colours will look a bit cartoony and unrealistic.
