[ESS] Modify highlighting colours for character strings in R buffers

[Gavin Simpson]

Dear list,

With the new version of Emacs with the nice font support now released,
I'm finding it a bit more difficult to read strings in R buffers due to
them having a light purple/pink colour. I find this colour blends into
the background a bit too much for my personal taste.

Is there a way to customise the colours used for character strings in an
R buffer?

Thanks in advance.
