If we take a look at well-known Web 2.0 sites, it's not hard to notice that their background images are mostly white [considering the ease of visual perception], so for us, we need #FFFFFF, and we should unhesitatingly choose white. As for the body font, there's no need to keep it unique; the best choice would be the widely-used Arial font [see "Branding with Arial"], then set the font color to gray [color: gray]. We also need to adjust the default font size [this depends on personal preference; default settings tend not to catch people's attention].
