Some color-blind or visually impaired people may want syntax
highlighting but not colorization. I think that was the original reason
for this request: rendering HTML with no colors for better contrast in a
specific terminal configuration.

In HTML we can specify colors explicitly or indirectly through styles
(equivalent to syntax highlighting). Viewing a web page without color,
therefore, is different from viewing it without syntax highlighting.

So maybe Emacs could offer a way to turn off colors without turning off
syntax highlighting, at least in SHR. I think it would be generally
useful, but don't know if and how it could work generally.

(I also agree that `colorization-mode' and `syntax-highlight-mode' are
better names for `font-lock-mode'.)
