In some color-schemes the "LEDs" of the binary clock look inverted: A 0 looks like a luminous LED, and a 1 looks like a dark LED. Please provide an option to invert the appearance of the leds. Maybe this could be implemented by swapping the colors the led states refer to, or by inverting the bits at logical level.
There will be a hidden setting to define a foreground color for the clock widget, right now this should be possible using a custom .gtkrc-2.0
