With the introduction of the transparent panel in the overview, we started making the panel text/icon color slightly brighter in the overview and on the lockscreen to ensure best contrast. Now unfortunately, setting the text color incurred a relayout of the underlying ClutterText actor (fixed with https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1750), and setting the icon color causes the icon texture to get regenerated (fixed with https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/932). Regenerating the icon texture will replace the icon actor, which also causes a relayout. This relayout of the panel has been measured to add at least 1 millisecond (the numbers fluctuated a lot) to about 5 ms it takes to layout the first frame when showing the overview. Since https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/932 is unlikely to land this cycle, this commit proposes a different solution: Simply don't use a different color for text in the overview. To avoid issues with contrast in the overview, make the default color slightly brighter and change it from #ccc to #ddd. Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1733>
