I can see the point that too many program elements get too much color, but:

Suggesting to not color keywords and use a single color for the names of top-level elements at the same time simply doesn't mesh well.

I'm coloring keywords exactly because I do not want to invent a new color for each individual top-level element name or require backtracking from the (in his proposal) highlighted name to the (in his proposal) non-highlighted keyword preceding it.

Looking at the code example here I'd be open to have less things highlighted, but where to start? I guess parameter names, but apart from that?
