How do I improve the color of photos?

Please see below two pairs of photos. You'll notice that the photos taken with the 350D have more true-er greens whereas the photos of the same object with a 650D show a more yellow-ish tint.

(Note that the lenses used are different, but I've tried swapping the lenses and it did not make a difference).

What do you suggest is the cause for the different greens? What do you suggest I change to make the photos from the 650D have the same color as the 350D?

Photo of grass with Canon 350D. Green of grass looks like a true color.

Photo of same grass with Canon 650D. Green of grass looks like it has more yellow.

if you are shooting jpg (not RAW), then there are several settings in the camera that effect this. You can set picture styles, or you adjust color balance, and/or white balance, all of which can affect the output. The 650D looks warmer. so you might want to reduce the yellow a bit. Check if white balance and picture style settings are identical between the cameras. If so, then adjust the tint to how you want it. Note, that overall proper color calibration is not trivial. It starts with your monitor, where you can't be sure that it shows the colors as they should, if it's not calibrated. You would have to buy a color chart, and then make sure that the final picture on the monitor will be as close as possible to the color chart when you hold it next to the screen (consider also the room light then, that falls on your color chart inside - best would be daylight, the same as when you took the picture outside.
