Colour Watcher and Colour Spaces
This page investigates how the visual colours change with different colour spaces.
I've saved all the wee gradient images (on the left) at maximum resolution and converted them back to sRGB (if necessary) in the hope one can see the differences.
All the scan/plots were taken while the image was in the appropriate colour space - they would, of course, change if converted back to sRGB, presumably for the worse.

and the image

The Red channel is boosted quite a bit for Red and Magenta colours.

Wow what are those red spikes doing in the green colour? |
 |
| CMYK
Notice how muddy the colours look, especially the cyan and magenta. The red channel in the green colour is truly amazing - starts off at over 100, becomes normal in mid-tone and then bounces up again. - just reminds me never to use this colour space during post-processing! |

If you want to experiment, then get the Watcher and read the Help (for Calibration).
I trust you found this interesting! - but what does it mean?
