It's easy to get side tracked by some cases that exhibit all features 
and therefore look neat.

I admit I only looked at it from the figure and didn't re-read 
everything in context, but I keep running into people having real issues 
with not getting the canonical reordering (or the fact that NFC starts 
with NFD and only re-composes after reordering.)

This leads to claims that there are normalization exceptions when all 
those are are unnormalized partially precomposed sequences that would 
not work if NFC tried to compose them directly, but do work if they are 
first decomposed (as is the case).

So I would step back from all the colors and ask what do we really need 
to get across. And second, is putting everything into a single table the 
best didactic tool? Having that much of an issue with colors tells you 
that there may be an issue.

Finally, I have come across people who can't read a sequence when it 
line-wraps inside a table cell; they read each line as alternative 
representations for the same thing. Breaking apart that humongous table 
would allow wider columns.
