Daniel Boles 7c809cfb73 Adwaita: dark: Make colorswatch.light tick visible
It used $text_color unconditionally, but in :dark, text is white, so we
overlaid a white tick on any light colours, all the way to white itself.

Using these named colours doesn’t make practical or semantic sense.
Instead, use white/black over dark/light swatches, as in HC, so all
variant–swatch combos work. Light looks the same, & :dark works now.

For backdrop, use alpha 0.5, unlike 0.7 in HC, as that seemed excessive
& different from the current effect. 0.5 is almost identical to how
$backdrop_fg_colour is a 50% mix of $fg_color, & matches backdrop text.

Summary
-------

* Do not edit the CSS directly, edit the source SCSS files
* To be able to use the latest/adequate version of sass, install sassc
* The configure script will detect whether or not you have sassc installed;
  if you do, it will regenerate the CSS every time you modify the SCSS files.

How to tweak the theme
----------------------

Adwaita is a complex theme, so to keep it maintainable it's written and
processed in SASS. The generated CSS is then transformed into a gresource file
during gtk build and used at runtime in a non-legible or editable form.

It is very likely your change will happen in the _common.scss file. That's where
all the widget selectors are defined. Here's a rundown of the "supporting"
stylesheets, that are unlikely to be the right place for a drive by stylesheet
fix:

_colors.scss        - global color definitions. We keep the number of defined
                      colors to a necessary minimum, most colors are derived
                      from a handful of basics. It covers both the light variant
                      and the dark variant.

_colors-public.scss - SCSS colors exported through gtk to allow for 3rd party
                      apps color mixing.

_drawing.scss       - drawing helper mixings/functions to allow easier
                      definition of widget drawing under specific context. This
                      is why Adwaita isn't 15000 LOC.

_common.scss        - actual definitions of style for each widget. This is
                      where you are likely to add/remove your changes.
                      
You can read about SASS at http://sass-lang.com/documentation/. Once you make
your changes to the _common.scss file, GTK+ will rebuild the CSS files.
