You might have an easier time with it if you increase the text size a little.

Or used black text on lighter background like most of the rest of the world.

Make the point. A color show differently to different people and the hardware setup. Instead, #ccc is specific.

The problem is dark backgrounds rarely work well unless if you have nice OLED display. I know they are cooler, and its the current hotness among young people whose eyes haven't started to give out yet...but dark themes really are limited by current LCD displays. Not to mention, everyone has a different display as well as eyes, and you can't really predict how the text will bleed from one viewer to the next!

This is what I get from being married to a visual designer.

Awesome, cheers!
