add a settings variable for background colour (refactor only)

[equivalentideas]

The background colour of the site seems to be a common thing to change in an alaveteli theme, see:

Adding a variable in _settings.scss would mean one small thing less to override in _custom.scss and would make things a little clearer. Just a small thing I came across.

Is your idea that themes would then override _settings.scss as well as _custom.scss or would they set the variable for their site some other way?

The way we're doing it in Right To Know is overriding with our own _settings.scss and then also naming some new variables in _custom.scss.

I think overriding the _settings.scss where possible is nice because:

• saves you having to override styles, which is generally more complex and it's easy to impact the site in unexpected ways. Just changing a variable that's been set for me by the framework gives much more confidence in making changes.
• easier to maintain, both because you're relying more on alaveteli and _custom.scss is smaller/simpler.

OK, makes sense.
