I have found the following diagrams helpful. (With acknowledgement to the Colour Collective, Warwick UK)

To be honest, I have stared at those two diagrams a lot, both last night, and again this morning, and the only difference I can see is that the B does not have an arrow next to it in the second image.  What am I missing?

Sorry, I didn't mean to keep you up all night  Grin  Embarrassed
The arrows are meant to show the change in one particular colour as it is converted. With RC, a colour outside the gamut moves to the edge of the gamut (de-saturated in effect) and a colour in gamut stays the same. With Perceptual, all colours change, compressed into the gamut, rather like compressing a soft ball into a smaller size.
I hope that has not confused you more. If it has, I hope someone else (like expert Mike maybe) can explain it more clearly.
I've been slowly learning about CM over the last 4 or 5  years, it's a long learning curve  Sad

I do understand what the diagrams are supposed to show, its that neither of us can see it.  Thats why I said the only difference I can see is that the arrow is gone from the B in the second diagram.  Any other difference is too subtle for either of us to see it.
