Update: this does sound off-topic, but I wrote it to respond to the conflict that was beginning about the "color palates" of Nikon vs. Canon, a conflict that is fundamentally flawed.
The "color palate" of cameras, lenses, and LCDs which I hear about so often is a figment of photographer's imaginations. The only thing a lens has to do with color is separating between color contrasts (low chromatic aberration). The only thing a camera has to do with color is its AWB. The only thing an LCD has to do with color is its calibration (and color spectrum coverage); miscalibration might result in the color being displayed improperly during playback but has zero to do with the actual image, as someone correctly noted by distinguishing between the LCD and the monitor (although the monitor might also be calibrated improperly).
By setting the white balance manually, using both axes that Canon and Nikon make available, not just a one-dimensional Kelvin scale, you can make the colors perfect in the actual image that is recorded digitally. (The reason there are only two axes but three colors is because the third color is determined by exposure, so it is only necessary to control with two variables the proportion between the remaining colors. It is just like the degrees of freedom in statistics, which for a one-sample student's t distribution is one less than the number of data points.)
There is no such mysterious thing as one brand of lens having "warmer colors" or all this other nonsense. Colors are a completely relative thing with digital photography, and even the RGB simulation of color is just a representation of the color spectrum which is actually an interval of the wavelengths of light. RGB colors are unnatural compared to sunlight, and it is just a blessing that our eyes and brains are complex enough to create the illusion of full color from a mixture of RGB.
So since colors are completely relative and white balance completely controls them (except for chromatic aberration), there is simply no such thing as a color palate of a camera or lens, or anything else.
The only thing that might be partly true to say is that the AWB doesn't work the way you see things with your eyes. But that's what you deserve if you are using AWB anyway--it gives someone else's interpretation of color rather than your own. If you want your photography to be determined by the color tastes of an engineer in Japan, then go ahead and use AWB.
And even then you can't blame AWB, because AWB can be fully adjusted so that it delivers your color tastes but still automatically adjusts for different lighting contexts (within the imperfect limitations of technology to detect such things properly, of course).
It's just a shame to see people believing that cameras have "color palates," when it is actually fully under the photographer's control.
Even among professionals, those who are willing to learn to get color right are in the minority. I see so many "great" pictures that are just terrible because those who processed the RAW files don't know anything about white balance, and because the photographer didn't do their job on site to set (or even take any photos of subjects that would have provided the needed data for) the proper white balance.
For example, there was a photo of a bee and sunflower on here. The white balance on that was not quite right. I have done extensive sunflower photography jobs and know quite a bit about it. The bee was OK, but not the background and colors. (I shouldn't judge this though. On the original user's monitor they may have been perfect, but on my precisely calibrated screen they were considerably off.)
P.S. The way to assess "perfect" white balance as I alluded to, is simply to hold a print from your photo next to the original subject. If the colors are not the same, then the white balance is off.
