Ask HN: why doesn't HN use my windows settings for text color like every other website?

the dialogue box I am typing this in takes its color value from windows XP settings on my machine. However, HN is the only website I have encountered where the text color is not also taken from my settings. So instead of a nice green text on black windows like every other website I wind up with black text on a black background. has anyone else had this problem? Is there a simple fix?

every other website either uses both text and background from my machine or their own. this mix and match causes the problem.
