I read once upon a time - and can't find it now - that white or yellow text on a dark blue background was the best combination, and that's why a lot of Microsoft curses-type software uses that scheme (e.g., edit.exe).

The contrast ratio is far more significant than the exact colors. I’d recomend using a WCAG (Web Content Accessibility Guidelines) conforming contrast checking when picking colors. A 4.5:1 ratio is recomended for normal size text. Here’s a simple web based one: http://colorsafe.co/.

While this will sound snarky in a way I don't mean it to, there are people who will reflexively scream the contrast is terrible how can any of you read any of this if your colors aren't #FFF on #000 or vice-versa. I've lost count of how many times I've come across folks insisting that, say, #444 text on an #EEE background is utterly unreadable. (In fact, it's an 8.4:1 contrast ratio, and easily passes the WCAG's more stringent AAA guidelines for normal text.)
