I use the strange, alien code #CEC4BA. It's the colour of my cats and generally easy to read against a black background.
If I'm honest, it's a slight struggle to read half the posts here. The fonts are often too small- and the colours far, far too dark to read without straining one's eyes. I find the default font's pretty much the only one I can read without issue-- and I can't read dark reds, dark greens, dark blues, dark browns etc. without highlighting the text. I'd recommend favouring legibility over 'style'!
