Pretty straight forward, see URL for a snapshot. Tried on several different midnight themes.
The CPU temperature by default is in Black, but it does not change to white using the dark theme.
I am not quite sure whether I really want to turn the default of black into the default foreground of the theme, especially as nowadays each sensors class has its own color assigned semi-dynamically. And from the very first versions on, colors could be adapted easily anyway. Any more opinions on this?

This is embarrasing; I actually didn't notice I could edit the temperature in Sensor plugin > Properties and double-clicking. On a tangent, could the "Sensors" text label be set it to the theme's fg? I think code should be: gtk_widget_modify_fg(sensors->panel_label_text, GTK_STATE_NORMAL, NULL); But I can't manage to apply this (what I've tried with 0.10.99.6 is in attached patch)
theme-independent concept of colours in sensors-plugin solves the issue automatically.
