A serious reply to the threadstarter would be:
Yes, the Canon cameras are indeed quite different in their basal behavior. Their newer models - since the 50D and forwards - all share a common trait.
What really should be a "red" color filter on the sensor is a lot more like "orange-red" in a Canon camera. This has both pros and cons.
Pros:
- The camera is less sensitive to shifts in light spectral composition - people don't turn as "greenish yellow" under fluorescent lights as with cameras with better hue resolution
- The skintones, which are mainly yellow-orange-red in base hues shift less in luma (you get "smoother" skin color)
- Having less hue resolution in the green - deep red region does also help with having a smooth, natural luma contrast in that range
Cons:
- The camera will have trouble discerning between deep orange and strong reds
- The skintones, which are mainly yellow-orange-red in base hues are more affected by noise at higher ISOs, since the base color correction matrix has to work harder with Canon filters (higher negative coefficients)
- Greenery will show less hue-resolution, and less luma contrast. The camera will have more trouble discerning between two similar (but not identical) green colors.
- As ISOs rise, the effect the higher strength color correction needed to get "normal" color out from the raw file increases chroma noise by about the square of the correction sstrength difference - hence the strong magenta-green chroma noise in a non-noise-reduced Canon high-ISO raw file.
Now, if the points are really pros or cons will be up to each for him- or herself to decide. For some a pro might move to the con, and vice verse.
Some (quite a lot of people - in my experience) do also prefer the original 5D (and 10-40D) color to the newer model colors. The original 5D, and in part also the 1Ds mkIII have a much higher green-yellow-orange band hue resolution, and they also render greenery and nature photography quite differently. Better? Some think so, some don't.
