Across the top of the panel, I have these status indicators: Language, Network Connection, Messaging, Volume, Time, and System.
Upon format and fresh install of 13.10, I see that Language icon does not change from white to dark grey when switching themes from Ambiance to Radiance. But whatever, I installed Unity Tweak Tool and a custom icon theme (Flattr) and window theme (Nitrux).
Now all my status indicators -except Time and Language- are stuck as grey, even though Niturx is a 'dark' theme. They are hardly visible.
And Language is still always stuck as white.
White .svg files exist for the indicator icons, and they appear when the launcher is called.
What's up with the Language indicator icon? The problem existed before any applications/files were added. What's up with my icons not changing color? The theme obviously supports it, it's just not happening.
