Over the years, I have used different sensors, including the Kodak SLR/C, which I like the colour very much; the Canon 1D with a 4 MP CCD sensor with vibrant colours; the garden variety of Canon CMOS sensors, with very please colour pallets; there is still the Panasonic LiveMOS, with similar colour signature as the Canon 1D; and of course the Sony CCD and CMOS sensors in various Pentax cameras and the NEX series.
Can't say I prefer one over the other, although in some situations, like skin tones, the Canon does look more pleasing to the eyes. All these sensors are a wonder of engineering, which allow us to capture memories with vivid details at the price so affordable that we could only dream of a mere decade ago.
