Seems to me that certain colors in certain light situations just are not captured accurately by our (digital) cameras.* The “little” one, the Lumix, has a hard time with deep blues and purples. It looks like the “big” one, the Canon, struggles with the reds, although it’s pretty close (this is natural sunlight).
* Could also be that I don’t know what settings to use, and that the camera sensor systems are tip-top.
