Perception varies as much as do our brains. I am visually irritated and
distracted by a highlight on the xterm adjacent to the one I'm working
in. Colouring words just reduces their readability, I find, and see no
obvious reason to use it merely for confirming attributes which a word
already has without. Using it only as an alarm, as in spellchecking,
works well for me.

It may be that coding in assembler for more than a decade (last century)
ingrained an eye for detail, and a mindset which connects disparate dots
with some facility. When you've had to remember what's in which register
right through a long routine, and infer the braces, subsequently keeping
rein on a bit of 'C' is no biggie.

In short, colouring all 'C' keywords, merely because they are keywords,
strikes me as equivalent to this comment in usefulness:

elephants++ ; // Increment elephants.

(Incidentally, the example is not artificial. Such facile comments have
been produced by folk paid to program.)

Folding, which you mentioned upthread, is something else. Through
hierarchical information hiding, it helps impart greater structure to
voluminous text, and I wouldn't be without it. (Even in .vimrc, now. ;)
